How can I test this on my PowerBook?
Hmm, since vbo branch merge all elts are always 32bit. I've looked a little at the code before the merge and I couldn't find any big endian specific code for elt handling, but maybe I just haven't looked hard enough. mesa/progs/trivial/draw2arrays is using unsigned bytes as indexes, change it to unsigned shorts and check if the rendering is correct.
