Hiya

I get this oops on boot when booting a kernel with pnpbios turned on
on a old thinkpad 600. BIOS seems to be pretty broken on this one, so that
might be a partial cause. Kernel is a pretty recentish fedora devel one
so it's basically 2.6.8-rc2'ish in case that matters. 

Might contain a few typos, couldn't get a readable photo :-(

Unable to handle kernel NULL pointer derference at virtual address 00000020
