The FreeBSD "slice" notation seems to be the current consensus. In it,
my DOS partition in MBR slot 0 would be sd0s0c -- my boot partition on
the NetBSD slice would be sd0s1a.

Its not perfect, but its better than what we have now, and its
reasonably compatible with FreeBSD's notation which isn't any worse
than any other notation we could use.

We need to move to 32 bit device numbers first, though -- the current
16 bit ones aren't going to be sufficient.
