Bug#509960: grub-probe: Support for partitionable md RAID devices (/dev/md/d#, /dev/md/d#p#)

[Julian Mehnle]

Package: grub-common
Version: 1.96+20080724-12
Severity: normal

GRUB 2 does not seem to support installing to partitionable md RAID
devices such as /dev/md/d0 or /dev/md/d0p1.  When attempting, e.g.,
`grub-install /dev/md/d0`, it says:

| grub-probe: error: Unknown kind of RAID device `/dev/md/d0p1'
