I think it works if patition XX?a is the top of the NetBSD partition,
but it fails if XX?a is in other place or there is no XX?a.

BTW, why does ARM disksubr has MBR supports? (in disksubr_mbr.c)
For shark or cats? To use disks written on i386?
Anyway, bounds_check_with_label() on i386 does not check MBR either.
It just use 'XX?c', and I guess it's the reason RAW_PART on i386 is 'd'.
