FileVault and Time Machine in Leopard

After planning to do an archive/install, I went with the upgrade with almost flawless results. I had to disable some login items for one user, but the machine seems to be running fine now, except for one problem:
It appears FileVault is not compatible with Time Machine. On first run, TM gave the dialogue box saying that this VERSION of filevault in incompatible, that the user's directory will not be backed up, and something about system restore. If you, too, had this warning, please post the exact words. I'll know soon if the FV account is backed up and will update the thread. This raises a few questions for me:
1. Would a clean install with a new filevault-ed user be compatible with TM? Is this only possible with a clean install?
2. According to http://www.macintouch.com/leopard/faq.html#tm -- Time machine handles filevault users when they log in, which makes sense, but I can't find anything at apple.com with this.
"How does Time Machine handle multiple user accounts?
Time Machine backs up all user accounts on the Mac (unless they are specifically excluded). It has special handling for File Vault accounts, creating encrypted backup disk images. These are backed up and updated only when that File Vault user is logged in."
3. If the above is true, does time machine write to an encrypted volume on the backup, so the files are not cleartext on the backup drive?
4. My previous backup was weekly with with SuperDuper, from an un-FV'd admin account. It copied the sparse.image of the FV'd user each time. This is multi-GBs and not feasible on an hourly basis with TM. Is there any way to use FV and TM?
I would be grateful to anyone who has some knowledge about the time machine and filevault to reply to these questions directly or describe how they interoperate.
All the best,
fellow

I had a similar experience: Time Machine warned me that the version of FileVault I was using was not compatible. I tried to fix this by turning off FileVault and then turning it back on again. This should, I believe, have the effect of deleting the sparse image and create a new 10.5 style image that is compatible with Time Machine.
That done, I can't figure out how to make Time Machine recognize my newly vaulted home directory. When I turn Time machine off and on again it seems to work, but it doesn't do anything to either recognize or complain about my home directory.
Hopefully someone has gotten past this point or knows how to make Time Machine see the new home directory image.

TimeMachine appears to have a strange behavior with FileVault.
1 - If you use an Old encrypted file (from 10.4), it cannot backup data
2 - If you do as requested by the system : Disable and renable Filevault (took about 2 hours for me...ough...) it works, but only save data when logged out. For me, it saved data when I logged out.
=> Filevault is completely unusable with TimeMachine and TimeMachine become useless...This should be fixed ASAP for professional users.

FYI...
FileVault and TimeMachine don’t play well together regardless of the version(s). If you enable TM while FV is active you get a dialogue explaining it will only backup when the users loges off and you can not do a single file restore or browse time machine backups.
In essence TM becomes useless when used in conjunction with FV. This was a pretty disappointing realization to say the least. The lack of compatibility between these two features is – unacceptable to say the least.
Note: If TM is activated before FV you don’t see the warning message.

I'm absolutely Miffed!! I can't believe Time Machine does not work with File Vault at the file level. This does the end user absolutely no good. The end user should NEVER be forced to choose between keeping files on their laptop "encrypted" OR backed up with Time Machine and NOT encrypted just to use it.
For professionals, this must be addressed.

Add me to the list of people who need FileVault and TimeMachine (and TimeCapsule) to play well together. This is an urgent need. Or, if it is impossible, then I need an open discussion of alternative ways of encrypting and backing up sensitive data.

I would turn off FV and use a FlashDrive or other external device to store "sensitive" data.
