When the rumors about mythical ;) performance in commercial flagging
with fine-optimizing came up I rescheduled all builds for i686 and
athlon. Using apt you should have the matching arch anyway now.

rpm -q --qf '%{name} %{arch}\n' mythtv

So anyone can try to benchmark the different builds. I would already
be surprised if you would gain more than 5% better performance though

Is it possible to have a kernel module out of this or a patch for v4l
rpms? :) :) :)
