But there _is_ no 169 partition on the second disk: its FreeBSD-only.
It has a 165 partition and no 169 partition. So NetBSD is going to warn.

Its not like this is a particuarly rare case, since for 1.3.x users,
thats the only way to get FreeBSD and NetBSD to coexist (or for
-current, before Duncan's patch went in.)

and you're not the only one to make the same mistake...  the crucial
point is that an ID of 165 isnt wrong at all, in the case where its on
a FreeBSD partition on a non-NetBSD disk:).

Perhaps eventually (2.0? later?) the warning should be
"No NetBSD MBR partition found, using FreeBSD partition"...
