With this [0] partition table grub-probe currently loops forever:

kern/disk.c:389: Reading `hd1'...
partmap/pc.c:142: partition 0: flag 0x0, type 0x5, start 0x0, len
0x11177330
partmap/pc.c:142: partition 1: flag 0x0, type 0x0, start 0x0, len 0x0
partmap/pc.c:142: partition 2: flag 0x0, type 0x0, start 0x0, len 0x0
partmap/pc.c:142: partition 3: flag 0x0, type 0x0, start 0x0, len 0x0
kern/disk.c:389: Reading `hd1'...
partmap/pc.c:142: partition 0: flag 0x0, type 0x5, start 0x0, len
0x11177330
partmap/pc.c:142: partition 1: flag 0x0, type 0x0, start 0x0, len 0x0
partmap/pc.c:142: partition 2: flag 0x0, type 0x0, start 0x0, len 0x0
partmap/pc.c:142: partition 3: flag 0x0, type 0x0, start 0x0, len 0x0
[...]

This patch fixes it, but probable there's a better fix.
