Can you copy down the oops? You'd need to do it by hand, and it's a very boring thing to do, I know, but it might be instructive.

Or a NULL pointer dereference that isn't seen by the Pentium machines because the pentium 4MB pages hide the problem (the kernel NULL address is actually mapped to physical address 0 on Pentiums). You can try this by undefining "USE_PENTIUM_MM" in asm-i386/pgtable.h and see if the pentiums crash..
