Thanks.  That's enough for me to add it to grub-mkdevicemap.

Now what troubles me here is that grub-probe is working now, but my patch
wasn't supposed to fix anything in it.  This seems to be inconsistent with
your previous report.

Are you completely sure that with your /boot/grub/device.map being:

(fd0)   /dev/fd0
(hd0)   /dev/vda

and grub-common being the pristine version, grub-probe failed and (in
consequence) regenerated your device.map?
