You mean XFree86 4.2.0.

Very commonly reported bug.  Someone reports it to me about once 
every couple of days.  I don't have any i8x0 video hardware to 
test with however.  The problem is widely reported so I figured 
it was just due to the developmental state of current CVS, and 
that it will be addressed by someone before the final release.

If need be, I can provide gobs of bug reports to anyone who has 
the hardware and is interested in taking a poke at fixing it.

Hope this helps,
