That doesn't sound right. I don't think xorg has drivers incorporated 
into it. The drivers are separate. Either you are using ATI (open 
source) or fgrlx (proprietary). What does it say in your xorg.conf file?

Did you try GEM with both sets of drivers? I just looked up the ATI open 
source driver and it still doesn't support 3d accel for the r300 stuff. 
Did you try glxgears with both sets of drivers?

Should still find your camera no problem. But you should just try it.

Gnome, but I don't think that has anything to do with it.

Are you using openGL? You may want to check out PDP and PiDiP for your 
project as well. Come to think of it, I don't know if PDP and PiDiP know 
how to find a firewire camera. They work great with usb webcams...
