        hp300: Add support for Apollo Domain keyboard. From OpenBSD.
                [tsutsui 20110212]
+       disklabel(8): Disable COMPAT_386BSD_MBRPART. The related kernel
+               compat option was disabled by default four years ago, and
+               NetBSD has not used partition id 0x165 for much longer.
+               Meanwhile the presence of this code in disklabel can
+               cause sysinst to clobber FreeBSD installs on the same
+               disk. Those with very, very old NetBSD installations may
+               need to use fdisk(8) to change the NetBSD partition ids
+               from 0x165 to 0x169. [dholland 20110212]
