Nope, doesn't fix it for me.
On a side note, I do notice the same message in the system.log every time this happens:
hidd: setting surface orientation to 0 returned 0xE00002C2
Anyone recognize this?

I'm experiencing this problem not exactly during user switching as I have only one user: me.
I experience this problem when I return to the login window and then try to log back in. Usually it hangs after i've let it sit in the login window for a while e.g. overnight.
This is really frustrating.

Interesting error code you found. I'll have to look and see if my logs report that one as well.
And I, too, can confirm that even with only using a single user account, eventually the problem crops up at the login screen.'
One thing I seem to notice is that the problem is greatly exacerbated by 3rd-party Mac App Store apps. I would be greatly curious if you would try installing a Mac App Store app, like, say Twitter or something, leave it running and see if the problem rears its head even faster/more frequently. If I leave Twitterrific or Sparrow mail app up and running and switch to my wife's account, I can reproduce the problem after just one or two account switches.

Yep this thread describe the exact issue that I have recently started to experience.
it ony started happening the other day. I'm the admin account and my wife has another account. We switch accounts frequently.
'Tis really getting on my wick.
Interesting few comments made about 3rd Party MAS apps - The Twitter app has recently been doing funny things with scrolling ie not scrolling with my Trackpad. I'll try uninstalling that and see how I get on.

Yeah, that's exactly the behavior I've noticed in conjunction with the TrackPad problem. I've seen it with Twitter, Twitteriffic and Sparrow. Probably plenty of others, too, if I tried.
This behavior (scrolling/not scrolling or not refreshing/repainting the screen until you minimize/maximize the app) occasionally shows up in iPhoto, too. This often signals an impending OS-wide TrackPad issue requiring a reboot.

I've not yet launched Twitter since my latest reboot, but I think I have found a possible culprit. If the app is running when I switch users the trackpad stops working.
And the app in question...
...the new Skydrive app from those that are no strangers to system freezes and driver issues, why it's Microsoft.
Godda love em.

I'm having the same issue.
It's clearly to do with login/logout and user switching. It doesn't seem affected by other running apps, I use twitter but my wife doesn't and if she turns on the computer in the morning, then I login to my account the issue still happens.
Also, everything was fine on my system before the 10.7.4 update. Started instantly after software update finished, and now won't go away. Happens every time I login/out or switch users. Most of the time the trackpad will recover after a minute or two, but sometimes it locks up and requires a reboot.
Anyhelp would be great! Super PIA.

Kind of. I just restarted my computer a number of times, and for some crazy reason the problem went away. I wish I had a better answer then that, but I've been unable to recreate the issue since about 48 hours after my above post.

Also having this exact same problem. After switching between user accounts, the Magic Trackpad will not move the cursor, but it will click. Running Lion 10.7.4. Tried de-selecting "allow bluetooth devices to wake this computer" in the second user account, while keeping it in the admin account, but that didn't solve the problem. Powering the trackpad off and back on makes it work again. It's not a battery issue.

You need to de-select that "allow devices to wake computer" option in Bluetooth settings in both accounts you're switching between.
It won't completely eliminate the problem, but it will make it happen far less often.
