Part of 'lspci -v' I think useful are as follows:
00:0b.0 Host bridge:Apple Computer Inc.UniNarth 2 AGP
            Flags:bus master,66Mhz,medium devsel,latency 16
00:10.0 VGA compatible controller:ATI Technologies Inc:Unknown devce 5c63 (rev 01) (prog-if 00 [VGA])
            Subsystem:ATI Technologies Inc:Unknown device 5c63
            Memory at 90000000 (32bit,non-prefetchable)[siu=6k]
            Expansion ROM at 90020000[disabled][size=128k]
            Capabilities:[58] AGP version 2.0
            Capabilities:[50] Power Management version 2


'mplayer -vo cvidix xxx.avi' output:
[radeon] Found chip:RV250 5c63 [Radeon Mobility 9200 M9+]
[radeon] Device is disabled,ignoring
vosub_vidix:Couldn't find working VIDIX driver

'mplayer -vo fbdev xxx.avi' output:
Can't put VSCREENINFO

'fbset -i' output:
...
Frame buffer device information:
Name:OFfb ATY,Via_A
Address:0x9c008000
size:789432
Type:Packed PiXELS
Visual:PSEUDOCOLOR
...
ACCELERATOR:NO

And I tried 'video=offb:off video=radeon:1024x768-32',I only got a frazed screen and I could type 'reboot' just to reboot.
Is this caused by someting in Open Firmware or old kernel as you said?

This Radeon chip is not even recognized by the latest radeonfb in 2.6.9-rc3.

	Hi,

> I bought an Apple iBook G4 with RV280M9+(Mobility Radeon 9200) one month ago.And I installed Yellow Dog Linux 3.01 on it.But I can't set the resolution with "fbset" in console mode and "startx" give me info like "(EE) FBDEV FBIOPUT invalid argument" while depth != 8."dmesg" says something like "Using unsupported 1024x768 Open Firmware FrameBuffer...".The output of "fbset -i" is
> NAME OFfb ATY,Via A

That's offb, the Open Firmware Frame Buffer device, which is used as a fallback
for unsupported graphics cards.

What kernel version does Yellow Dog Linux 3.01 use? Does it include radeonfb?
Recent versions of radeonfb should recognize your Mobility Radeon 9200.
