Ah, i should have been more exact. I traced the code and grub runs fine,
loads it's second stage boot loader, and then early in second stage, it
switches to protected mode. I think it switches back and forth a couple
of times (prot_to_real/real_to_prot), but I never get over the very
first switching that occurs at all. But it does hang every time.
