Default Bug#572385: linux-source-2.6.33: radeondrmfb resizing is broken

Package: linux-source-2.6.33
Version: 2.6.33-1~experimental.1
Severity: normal

Setting the resolution of the radeondrmfb frame buffer console doesn't
work correctly:

# fbset -v -i
Linux Frame Buffer Device Configuration Version 2.1 (23/06/1999)
(C) Copyright 1995-1999 by Geert Uytterhoeven

Opening frame buffer device `/dev/fb0'
Using current video mode from `/dev/fb0'

mode "1024x768"
geometry 1024 768 1024 768 32
timings 0 0 0 0 0 0 0
rgba 8/16,8/8,8/0,0/0
endmode

# fbset -g 1280 1024 1280 1024 32
ioctl FBIOPUT_VSCREENINFO: Invalid argument
# fbset -g 800 600 800 600 32
[resolution doesn't change, console uses the left right 800x600 portion
of the screen]
# fbset -g 1024 768 1024 768 24
[text changes to multicolored with light violet tint, console uses the
left 75% portion of the screen, characters are 75% of normal width]
# fbset -g 1024 768 1024 768 16
[text color changes to magenta, console uses the 50% left portion of
the screen, characters are 50% of normal width]
# fbset -g 1024 768 1024 768 8
[text changes to multicolored with yellow tint, console uses the left
25% portion of the screen, characters are 25% of normal width]
# fbset -g 1024 768 1024 768 32
[restores the initial state]
#

The above commands produce no dmesg output.

Please provide a way to change the resolution of the console, either on
the radeon module load or dynamically (preferably both).
