[BUG] unable to handle kernel paging request in next-20080516

Sometimes when booting next-20080516 on Ubuntu Gutsy an oops then a panic
will occur. At first I thought it might be provoked by vga=0x164 but this
does not appear to be the case and the issue is seemingly random. I've
hand transcribed the oops so there may be errors in it but hopefully it
will still help:
