Subject: problems with 4 MB VRAM Diamond Stealth

hi :)


I have a 4 MB VRAM Diamond Stealth (2 MB on board and 2 MB expansion
from Kingston, designed for Diamond Stealth VRAM). 

All possible 2MB or less video modes (for example 1024x768x64k)
are working fine. But all 4MB modes (for example 1024x768x16M
or 1280x1024x64k) are not. 

There are vertical stripes on the screen, some fonts are garbaged, 
some random color pixels appear on white surfaces...

I'm using 2.1.0 Release, with its default XFree86.

This hardware works correctly under Windoze.

Does anyone have a solution?
Or at least any experience with other 4 MB cards, especially
ATI Mach64?
