What I was getting at was that since the PROM's only real business
in knowing where the end of the disk is could be to check whether or
not the boot partition is within scope, it won't care really about
partitions being an even number of cylinders.

I.e. if it uses the 'c' partition to do this (but really ignores the
partition table for 'c' and instead just looks at the disk geometry and
calculates the end of the disk ala NetBSD), then it shouldn't care about
the exact size of the boot partition -- only where it starts.

Of course all of this is pure conjecture in an attempt to devine the
operation of what may in fact be several or many different versions of a
black box.  I'm definitely not a Sun PROM expert, although I'm fairly
proficient in using most of the older variants!  ;-)
