Jason replied back to me directly after my first reply and pointed out that some non-free X drivers might not support multiple X server instances, but looks like that doesn't affect your situation. Maybe it'll help someone out someday in the archives.
I've got the nVidia drivers on a Debian woody system with kde2 configured for multiple desktops, and last I checked, it worked OK.
FWIW, I discovered how to do this in much the same way as you described, by following my nose through the files. I may have done some find'ing and some grep'ping, but in general I'd say looking for related files in /etc is always a good place to start.
