I have never tried it, but if you use Toast to simple duplicate the CD, won't it copy it identically to the original?
When making a copy of the Leopard install DVD, which has both Mac and Windows filesystems on it, the copy works fine in both Leopard and Windows.
It seems to me that a clone is a clone and does not care how the data are formatted.
Of course the system hardware does have to be able to read the CD.
I'm not sure what you mean by mixed mode but disk utility can make identical copies of CDs. For example, the leopard install DVD is dual boot (it has windows drivers to install if you use bootcamp). disk utility copies everything.
to copy a CD in disk utility, select the CD in DU and go to file menu->new->disk image from disk.

I would add, for the OP, that the disk utility image file is also a backup of the CD.
A mixed mode CD is a combination of one data track and and audio CD on one disc.
The computer sees the data track as one disc and the audio CD as another disc.
Backing up the CD audio portion of the disc using Disk Utility results in an ISO that is no longer an audio CD which cannot be played in a CD player.
Mixed mode CD's were common for old games from the early to mid 90's. You install the game from the CD, and then the game reads the rest of the disc a soundtrack.
I thought Disk Utility would make a byte for byte image of the CD, but it doesn't want to copy the audio tracks.
OS X doesn't use the standard /dev/cdrom location for your optical drive. Instead, the /dev/diskXsYY format is used for all disks mounted by the OS.
In order for this to work, you'll have to know where the disk you want is. Getting this info is simple, just open Terminal, and type 'diskutil list' without the quotes. This will give you a text representation of all of the disks you have mounted. To restricted the list to just the physical devices themselves, you can run 'diskutil list | grep -E [\ ]+0:' without the quotes to narrow down the listing. Either way, you're looking for the top level 'diskX' line (NOT diskXsYY) for the disc you are trying to copy.
0: GUID
partitionscheme *298.1 Gi disk0
0: FDisk
partitionscheme *14.9 Gi disk1
0: Apple
partitionscheme *19.1 Gi disk2
0: CD
partitionscheme Half-Life *706.5 Mi disk3
Depending on how many disks you have mounted, your results will vary. Once you know what disk you're looking for, the path to the disk is '/dev/diskX'.
However, it seems to be irrelevant, because attempting to run 'dd if=/dev/disk3 of=~/Desktop/TMP/Half-Life.iso' with the disk structure seen above yielded an unrecognizable iso file. This is the only disk I have laying around that I know is mixed-media, so YMMV. Good luck!

Does anyone know how to make an ISO out of a Mixed Mode CD?
Nope... and the reason is you don't make an iso out of a mixed media cd. You make what's called a cue/bin. The bin is an exact duplicate of the cd data (which is why it is often larger than the cd) and the cue is an index, showing information about each track.
There's usually an indexing/data track (very small), the program data - a very large track (this is what shows up as the data cd when browsing), and the rest is Audio CD tracks.
You need to find software that can create a cue/bin and mount it like a regular cd.
