Thats assuming my installer would install the relevant binary etc.
I don't know whether it's safe, but if it is: please do *not* install
one binary or another depending on whether altivec is available at
installation time. Currently, an installation of Mac OS X can always be
used to boot any machine supporting it, which is very handy. Doing this
kind of stuff would break this (very useful) functionality. Just do a
test a runtime and set a function pointer instead.
