2.4 series radeonfb (1.8-benh) works perfectly (also modular).
2.6 series new radeonfb never worked (since 2.6.0 at least), it does not sync here (laptop XSVGA).
After loading, fbset reports 1400x1050-60, as for the 2.4 version, but screen
is blank and stay in normal text mode 80x25. I need to switch on and back to X in order to
see screen content again. That's for loading it modular of course, I have to do yet test
for static version.

This is with current 2.6.8 in debian, but that's true with _all_ other previous versions (2.6.0+).
fbset return right mode, as set in /etc/fb.modes too:
mode "1400x1050-60"
# D: 108.003 MHz, H: 63.983 kHz, V: 60.191 Hz
geometry 1400 1050 1400 1050 8
timings 9259 136 40 10 0 112 3
rgba 6/0,6/0,6/0,0/0
hsync high
vsync high
accel true
endmode
I tried to fbset explicitly the mode after module loading too, but without results.
I'll return results with static compiled in module when possible.

Indeed, I also tried and verified. It is ok with latest 2.6.9 and current 2.6.10.
So closing.
