correct me if I'm talking nonsense. :)
As I understand it, the gcc vector extensions are only usable in gcc 3.2
(maybe 3.1), and you'd have to rebuild everything down to glibc with
-mabi=altivec if you want to use that. Maybe you rather want to use
Altivec inline assembly, which works independently from the compiler.
