From /usr/src/sys/amd64/conf/NOTES (9.1-RELEASE):

# Enable Linux ABI emulation
#XXX#options    COMPAT_LINUX

# Enable 32-bit Linux ABI emulation (requires COMPAT_43 and
COMPAT_FREEBSD32)
options         COMPAT_LINUX32

I think I first ran up against this when I moved to 9.0 some
time ago, but yes, amd64 uses a different kernel config
option than i386 for linux compat.

I tend to leave it as a module & load it if I perchance
need it. This also allows rebuilding & reloading the
modules without a reboot, should it need it.  The
modules seems to build fine without having to
fiddle about with kernel config jiggerypokey.
