There are a lot (and I mean LOT) of places where the disk sector number
is held in an int.  Much of the kernel was changed to use daddr_t (64bit)
but that doesn't help much since all the disklabel/mbr handling only
had 32 bit fields.
Clearly the 32bit values could be unsigned, but that only gives a factor
of 2 - and if you can build a 1TB disk, a 2TB one shouldn't be hard!
