Hi,

This is my first bug on freedesktop.org, I apologise in advance if the bug is
filled out incorrectly, or if you do not agree with the severity or priority.

Problem:
In X, whenever I select to:
* logout of X (ie: to switch user),
* shutdown,
* restart,
* Press the Ctrl-Alt-Backspace combo,
the system freezes and the screen goes black and reports "no input signal".
Ctrl-Alt-Delete doesn't do anything, and I don't believe the magic sysreq combo
does either. The Mac Mini cooling fans come on and spin at full speed. The only
option is to hold down the power button for several seconds to turn the PC off.
This means that the partitions aren't cleanly unmounted, and recovery is needed
upon the next startup.

System: G4 PowerPC Mac Mini with ATI Radeon 9200 card:
0000:00:10.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon
9200] (rev 01)

Driver: Compiled from this GIT repo:

    mach64: factor out BIOS panel info parsing

Kernel: Reproducible on 2.6.22 and 2.6.24.

Screen: 19" BenQ LCD connected via DVI, operating at 1280x1024/24 bit/59.9Hz.

In the past, I have had problems with no valid screens/modes detected, or blank
screen on x startup - hence my desire to try the latest from GIT.

I have attached my xorg.conf - and I have tried removing all "Option" lines
from within the "Device" section. I'm not running compiz as my card only has 32
MB RAM and doesn't support compiz at 24 bit colour @ 1280x1024.

I am happy to compile and test possible solutions.
