i've got something like this. check it out:
http://lists.freebsd.org/pipermail/freebsd-stable/2010-January/054551.html
i remembered this issue when reading your e-mail this morning.
unfortunately i couldn't fix the issue.
just saw the answer from Paulo[1] today (LOL).. but you, John, are
using "the same" entry with grub2.. so.... sadness ;-(
nowadays i'm using 10.0current with my asus 1005pe (eeepc) and
everything runs like a charm. i still have the same pavilion; maybe
one day it will run freebsd again (even if it needs 30min to boot) <3
