No, that patch is the only change I made.  I pulled the PCI ID from the 
r300 CVS, so they already have it.  If the r300 support in our kernel 
DRM doesn't work then I have accomplished nothing because I was just 
making the r350 look like an r300.  So much for the easy way...

Gotcha.  I was definitely confusing things.  Thanks!
