Yes, it can get confusing:
uname -s uname -m uname -p
----------------------------------------
Intel Q9400 (Core2 Quad):
FreeBSD amd64 amd64
GNU/kFreeBSD x86_64 amd64
Linux x86_64 unknown
32bit os (same processor):
FreeBSD ? (untested) ?
GNU/kFreeBSD i686 i386
GNU/Linux i686 unknown
----------------------------------------
Intel pentium 4:
FreeBSD ? (untested) ?
GNU/kFreeBSD i686 i386
GNU/Linux i686 unknown
----------------------------------------

The official 64bit OS name is "amd64" for FreeBSD, GNU/kFreeBSD and Linux.
However, uname -m gives differing results and depends on the version of the
running OS, not the real underlying processor; A 64bit processor can run a
32bit OS.
