Here is support for partitioned software RAID devices for
util/i386/pc/biosdisk.c.
You can now try grub-setup/grub-install on a partitioned RAID array, then boot
the result in an emulator.
A RAID array could consist of a single loop device.
Also linux_find_partition does not allocate enough memory to add the partition
number onto the end of real_dev.

* util/i386/pc/biosdisk.c (util/i386/pc/biosdisk.c):
Allocate enough memory for REAL_DEV. Support partitioned software RAID.
(get_os_disk): Support partitioned software RAID.
