Hi both Thomas's

I have worked up a patch to mesa git to include VIA's chrome9 kernel
module.  I have not had much success with it, but haven't had much
time to tinker with it either.  I have also been working on a patch to
via_accel.c via_dma.c and via_drc.c  to properly handle the chrome9
registers.  That is close, but also needs some work.  I will try to
get those into a publicly consumable form in the next day or two and
all other people to play around with it.
