First of all, let me say that I have no experience with multiple graphics 
cards, but I do have lots of experience with stereo.  That said:

There are several possible problems, swapping the cards or choosing a 
Quadro display as your primary monitor might help.  If you have the 
NVidia's Consumer 3D Stereo driver installed for the 7800GTX, it interfers 
with the Quadro driver's stereo, so remove it if it is installed.  Then 
enable stereo on the Quadro -- you need to go the "Performance & Quality 
Settings" dialog (Display Properties dialog, Settings tab, Advanced 
button, Quadro tab) and switch the View from Basic settings to Advanced 
setting, then scroll down and enable stereo and choose the appropriate 
stereo display mode.  Also, the Quadro FX 1500 is not listed as having a 
stereo connector, so your Quadro can't support all of the stereo display 
modes that other Quadro cards do.  Whether that matters or not depending 
on your other stereo viewing hardware.

Last, while you're trying to get stereo work, I would just start with just 
one graphics card in the system, the Quadro, and put the 7800GTX back in 
once stereo is working.
