For FreeBSD, kernel 80386 support is already disabled by default before
RELENG_5, also userland was disabled recently.  I think the support is
still there but just "disabled" by default for performance reasons.

IIRC DragonFly already did some optimizations that will prevent it from
running on 80386 (not really sure, but I think there is some code in
XMM/MMX optimizations that does prevents this) so you may want to replace
the 80386 code with the #else clause contents if that's true :-)

Cheers,
