Hah, sorry I forgot about that hunk.... 5231

I think you mentioned that a warning is generally good if people don't
set this explicitly... So maybe we should just fix what we know for sure
(most likely those with no SSE and SSE2) and wait for people to fix this
while they come along these CPUs/sockets... If nobody does, the warning
is maybe not critical for them ;)

Yes. Since one socket can choose multiple cpus, it must go in the socket
to be safe (otherwise a SSE enabled CPU might break a socket with a
non-SSE enabled CPU), but there are also CPU models that don't come in
sockets... "Fake" sockets? Better solution? Set it in the CPU for those,
with a comment?
