Just finished compiling world and kernel with the patch, no issues
whatsoever but i have some questions :)

I have a Q6600, with -march=native gcc still uses nocona instead of
core2, clang does the right thing. Is this a bug?
Is it possible to support sse4.1 for penryn or is there a problem with
the license?

Regards
