Evenin Aaron!

I get a slightly different message than you get both in xorg and
dmesg.  Before whipping it all out and comparing parts, did you add
the change to drm_pciids.txt at the VIA section?  Also, I made sure
that my BIOS was set for 32MB for the video memory size, this seemed
to be in a few HOW-TO's for Via hardware, so I did it.  After I
finally got DRM working with Via, I had to recompile Xine-lib and
mythtv to get them working with my new setup (even though I was using
the XvMC Wrapper lib).
