hm, what's going on here.
Why does partitions/msdos.c know about AIX at all? Is there something special about AIX partitioning which ties it in with msdos?
Now that we have AIX partitioning support, can we simply remove the AIX code from msdos.c? So msdos.c will say "I don't know what that is", and we fall through to aix.c which says "that's mine!"?
