radeonfb: ref_clk=2700, ref_div=67, xclk=16600 defaults

This line here says that radeonfb didn't acquire the pll clock values from
your BIOS properly and is using defaults, which are for the 1st gen
Radeon.  Is anyone else with a 9500 (or 9700) using radeonfb and can get
values from their BIOS?  (radeonfb will say "from BIOS" if it got them
properly).  This will explain your "out of scan range" problem because it
is not setting the mode right.

Hi,
I've a  Radeon 9500 Pro board  and framebuffer isn't working. If  I boot
with "video=radeon" monitor complains about "Out of scan range". This is
from the bootlog:

If   I  append   a  specific   video  mode   I'll  get   "out  of   scan
range"   or  "no   signal"  depending   on  the   video  mode. This   is
"video=radeon:640x480-16@85" (no signal):
