Maybe this is because arm/disksubr.c has MBR support
but unlike i386 RAW_PART is 2 (not 3) and it does not
have 'NetBSD parition' in its disklabels.
So, if a disk has MBR and NetBSD partition in it is not located
at the top, bounds_check_with_label() would fail.
Anyway, I guess bounds_check_with_label() should check
MBR if it exists, rather than using 'NetBSD partition'
in the disklabel.
