I had problems like this a couple years back when I was installing OS/2
on a Dell Machine (486,66mhz).. The installation would fail if I didn't
disabel both L1 and L2 caches.. But I ripped out the TsengLab GFX card
(VLB)
and all troubles went away.. Ripping out gfx card is often not a option 
but the Dell MB had a Cyrrus Logic Chip on it...
