Some notes of interest:

- the unaligned pointer error also seems to happen in real systems with certain ATI cards.
- rebuilding grub with mm-debug makes Ubuntu boot without unaligned/out of range pointer messages with -vga std.
- adding debug messages (with grub_printf()) to grub memalign/free functions in kern/mm.c triggers other reported behaviors including the boot loop, and more worrisomely, KVM_INTERNAL_ERROR_EMULATION.

These results obtained with stock Ubuntu 10.10 grub2 in guest (1.98+20100804-5ubuntu3) and 3.1.6-1.fc16.x86_64 host.
