Note: I assume you're running the latest grub2 from sid (1.94+20060926-1), cause
at the time you reported this bug there were other bugs that caused the same
behaviour in grub-probefs.

Ok.  grub-mkdevicemap needs to learn about /dev/md_d0, but maybe grub-probefs
does too (it has other, more generic pathname checks).  Please try:

  echo "(hd0) /dev/md_d0" > /boot/grub/device.map
  grub-probefs -v /

Thanks
