Bug#483971: Patch for squeeze: grub2 support for multipath

[John Morrissey]

found 483971 1.98+20100804-14
fixed 483971 1.99-12
thanks

grub2 1.99-12 (from sid) works fine, but I ran into this upgrading our
multipathed lenny machines to squeeze. Attached is the patch from #442382
that fixes this, updated for squeeze's grub2 (1.98+20100804-14).

FWIW, unmodified 1.98+20100804-14 on squeeze fails with:

[jwm at syslog01.roch.ny:pts/4 ~> sudo dpkg-reconfigure grub-pc
Generating core.img
/usr/sbin/grub-probe: error: no such disk.
Auto-detection of a filesystem of /dev/mapper/rootvol-part1 failed.
Please report this together with the output of "/usr/sbin/grub-probe --device-map=/boot/grub/device.map --target=fs -v /boot/grub" to <bug-grub at gnu.org>
