Benh suggested that I made this more known, and in particular to this list, so I send this mail in hope that some people might be interested. In particular, I ran the following benchmarks against libfreevec/glibc:
http://www.freevec.org/content/libfreevec_104_benchmarks_updated libfreevec has reached a very stable point, where me and a couple of others (the OpenSuse PowerPC port developer being one) have been using it for weeks (personally I've been using it for months), using the LD_PRELOAD mechanism (as explained here: http://www.freevec.org/content/howto_using_libfreevec_using_ld_preload). The OpenSuse guys even consider using it by default on the ppc port even, but that's not final of course. glibc integration _might_ happen if glibc developers change their attitude (my mails have been mostly ignored). Last, I've also been working on a libm rewrite, though this will take some time still. I've reimplemented most math functions at the algorithm level, eg. so far, most functions achieve 50%-200% speed increase at full IEEE754 accuracy (mathematically proven, soon to be published online) without using Altivec yet, just by choosing a different approximation method (Taylor approximation is pretty dumb if you ask me anyway).
