The pvr2fb driver is named as such because eventually we want to be able to
support all CLX boards, not just the chip found in the Dreamcast. Right
now it only supports the Dreamcast and only builds under LinuxSH - vanilla
kernels can't be targetted to the DC.

The main problem with writing this driver is that not only are the specs
from VideoLogic impossible to obtain w/out signing an NDA, the only
commodity pvr2 board that you can find (others have looked) is the
Dreamcast. I have Win32 pvr2 drivers to play with, but it's kinda useless
if I don't have a board to test.
