another, better workaround is limiting video mem size by a few (2-3) mb.
at least for cards with lots of video memory - for example 28mb is enough
for X (i have 32mb g400) so i never get mem corruption as x uses 0..27mb and
mga_vid/vidix uses 28..31

afair it's somewhere in the faq too, for mga_vid
