I think it is possible that the flickering could be remedied - I see no
flickering at 1024x768 and 32bpp, but I do at 24 or 16 or 8 bpp.  It is
also possible that your flickering is not at all similar to my
flickering and were talking about two completely separate problems.

There were some driver problems under windows a while back that
displayed the same problem for me. A driver revision ameliorated the
flickering (though did not eliminate it).  I hate to ask but does your
screen flicker under windows when the machine is hot?  If it does then
I'll have to agree with you.  One other test that occurs to me, do you
see the flickering on an external display?  If it is heat related you
