Bug#457233: xserver-xorg-video-ati: freezes system after a few minutes with comiz on rv370

this driver has always locked the machine randomly, but I could live
with it. The latest experimental version though is unusable: after a few
minutes the machine freezes (hard freeze, like a PCI bus lockup: not
even ping works, but the keyboard leds are blinking).
Note: the previous experimental version was more usable for me.
Frankly I really don't know what I can do to help, because once frozen
the machine is a brick. Does someone have a idea for that problem ?
There have been some changes regarding the default AGP mode (to fix some
lockup like yours on other boards). I guess it will help if you add
Option "BusType" "PCI"? Also, try changing your AGPMode in the Device
section (without Option BusType) and let me know which AGPMode works or not.
