Cool. I'll apply it as soon as I get back to my powerbook.

One thing though: I think this speaks more to the penetration of x264 with
linux ppc users, rather than the linux community as a whole. Case in point:
Cinelerra, a project I expect x264 developers have at least heard of, (
cvs.cinelerra.org), has been looking for an altivec maintainer for at least
a year now (I think). I finally got enough time to offer my services, and I
hope to make some contribution there, but I bet part of the issue is: mac
videophiles have a lot of alternatives in os x, such as Imovie HD (or more
probably a pirated FinalCutStudio) , Handbrake, and FFmpegX, and if they
want to use fink or darwinports they can get some of the straight linux
stuff without dualbooting.

Anyway, I'll get back to you when I can about the patch, and thanks again,

-griff
