This box doesn't have the lm flag.

                 +--- that's what you're looking for!

Also, if you have 64-bit install media around you can always just try to
boot it on the other hardware. The worst that can happen is it will fail
horribly during booting - it won't leave you with a borked install that
won't boot (since the 64-bit media will boot a 64-bit kernel during the
installation).
