Okay, thanks for clearing that up. I wasn't quite sure what the
relationship between DRI and DRM was. In that case, I guess bleeding-edge
DRM isn't as necessary. :)
Where is the kernel's CVS repository so I can just grab the DRM out of it?
Not wanting to download entire kernel source to rebuild a kernel for one
feature applies to not wanting to download entire kernel source to grab one
kernel module out of it. I suppose that at the very worst I could just
download the kernel source at the university and repackage the useful parts
myself, though...

Yeah, I've already figured that much out. :) I was originally hoping that
Matrox's drivers would actually be a proper set of 3D drivers like what
nVidia did, but it looks like they're just doing the cheesy "let's take
advantage of open source and roll in our own proprietary crap and take
credit for all of it!" crap that 3Dfx and Creative Labs are so known for.
