Done. Followed http://www.openbsd.org/faq/faq4.html#bsd.rd part of the
FAQ, and ripped the 3.8 bsd.rd from the usa.openbsd.org server. Just
for info, the bsd.38.rd reports the same df as the others...

Ok, this is strange:
=-=-=-=-=-=-=-=-=-
# fsck /dev/rwd0d
** /dev/rwd0d
** File system is clean; not checking
# fsck -f /dev/rwd0d
** /dev/rwd0d
** File system is already clean
cannot alloc 4294966928 bytes for inphead
# fsck -f /dev/wd0d
** /dev/wd0d
** File system is already clean
cannot alloc 4294966928 bytes for inphead
#
=-=-=-=-=-=-=-=-=-

I hope that helps some.. If there is anything else you'd like from
this box just let me know!
