Xorg log from crash

I have been experiencing random crashes with xf86-video-ati driver 6.12.2 (mesa
7.4) the crashes occur some time after login (1 to 2 hours or more, if I'm
lucky :)).
X restarts every time after the crash. After the crash I'm able to login
normally to KDE but if I try to VT switch or login to console the screen gets
corrupted. It displays the console but everything is garbled and compressed at
the top of screen. I need to reboot to be able to login to console.

It doesn't seem to exist a special event that triggers the crash. Although it
seems to occur more often when opening a new window, but also occurred in other
situations. This can be just a coincidence.

My system Configuration:
ATI Mobility Radeon X1600 - toshiba laptop A100 
openSUSE 11.1with KDE4 4.2.69 and desktops effects enabled and using EXA 
xf86-video-ati driver 6.12.2 (mesa 7.4).

Today I updated drm from git but the crashes continued.

I don't know if it is related but I also noticed one time the rendering of the
inside of the windows(2D) was really slow, but the desktops effects were still
fast and I couldn't notice an increase of the cpu usage. I tried changing VT

I'll try XAA to see if get the same result, but EXA is so great...

I don if it is relevant but I had the same problems the last time I tried the
radeon driver:
xorg 7.2
mesa 7.2
xf86-video-ati 6.9.0
opensuse 11.1  with KDE 4.2.0
With this configuration the crashes of the x server occurred usually just some 
minutes after login. In this case X didn't restarted, the desktop would get
frozen, some time with a jerky slow moving mouse, not even magic keys could
restart the system.
I don't have a log from this crash. 

I tested with radeonhd 1.2.5 but I also get random crashes, but with this
driver X doesn't restart the system just freezes.

With fglrx I dont have this crashes but I prefer the radeon one.

I'm available to give more info if need.
