Bug#564936: grub-pc: unexpectable reboot

[Cade Robinson]

I just had this issue on a 32-bit machine.
I went from 1.98~20100107-1 to 1.98~20100115-1 and was unbootable.

I wouldn't even get the grub prompt.  I would get the "error: no such
disk" and reboot.

I was able to boot a knoppix disk and mount up all my partitions and
everything hardware wise is fine.
I downgraded to 1.98~20100107-1 and I am able to boot but I do also get
the same error as in bug #564252, but at least I can boot.
