Well, for an MSDOS partition table, you would look for '253', for a
Mac partition table you could look for something like 'Linux_RAID' or
similar (just arbitrarily define some name beginning with the Linux_
prefix), etc. This means that the partition table type would need to
be exposed as well (I don't know if it is already).
