Currently i use 5.40.02.36.00. Before i had 5.40.02.10.14.
I had these Xid Messages and scrambles pixels all over the screen, too. The System was only stable if i set the Res to 800x600 or lower. If it was higher i could use X for 3 or 5 Minutes. When a 3D Screensaver started after this period of time the problems began.
It seems, that you expire the same, too. For me its only the BIOS 5.40.02.36.00.
Sine this Update the sys runs rocksolid for WEEKS.
