Hello,

radeonfb ignores the video= parameter and always run at 1400x1050 (the
highest available). Things where fine with .16-rc1-mm5.
I also tried booting with 640x480-32@60 without success.

# fbset -s
mode "1400x1050-60"
    # D: 108.003 MHz, H: 63.983 kHz, V: 60.021 Hz
    geometry 1400 1050 1408 1050 8
    timings 9259 136 40 13 0 112 3
    hsync high
    vsync high
    rgba 8/0,8/0,8/0,0/0
endmode

Oh, however running
	fbset -xres 800 -yres 600
works when the system is up.

This is the relevant dmesg snippets:
