The driver remains buggy, problem is either with asynchronous memory read from the graphics card or masking problem, who knows? At 768x576 @ 60Hz resolution the screen is almost undistorted, but at the resolution the Ubuntu 8.04 was trying to install (1600x1200?) it was close to impossible to navigate on the screen.

This may be a problem with the double-buffering or anything to do with memory access.

The distortion works this way:
some line address ranges get confused, so that whole columns may appear on a second location.

Even worse thing happened after I took the photo. I am not able to switch monitor resolution from the 1280x1024 to anything else!
