I already figured that out by myself.

Interresting.
I personaly dont know how the ATI architecture differs that a kernel
module might be unnecesarry. Fglrx also uses a kernel module.
That said i havent looked that deep into the existing modules to give a
qualified opinion.

I´ll invest a couple of hours now and then. Been a while since i last
did low level gfx card stuff and 3D, but i hope i´ll be able to
contribute a bit more than just some pci-ids.
