Please verify the rivafb patch is in there by
grep set_ivad_contrast drivers/video/riva/fbdev.c (while in the 2.6.0
source dir).
What rsync mirror did you use? Maybe it's not been updated lately. Ben
applied my patch on Nov. 16 FWIW.

If above test shows a couple of lines containing set_ivad_contrast, the
patch has been applied. Please check there's a OF property corresponding
to your the panel in your device tree (something with EDID in the property
name).
I've only had a 15'' flat panel iMac for testing, your display might be
different.

video=rivafb:flatpanel I suspect. You can also try forceCRTC=0 or
forceCRTC=1
If that still fails, 1) try to figure out what the 2.4 kernel thinks the
display is hooked up to, and what the display parameters are as read from
the EDID property, and 2) try to hard code that for 2.6. Also, have a look
at the EDID parsing code in 2.6 radeonfb.
