No need, with your latest version, both --disable-avx and with AVX all
tests pass for me, including fate.

Patchset with three patches staged here:
https://gitorious.org/~siretart/libav/siretarts-libav/commits/AVX.2011-04-25
I've already squashed Diegos cleanup commit onto the third patch. I'll
give folks some opportunity to cheer or shout on the patchset before
pushing it to master.
Great job!
