This should indeed be the version I had in mind as well - hell, already
1.5 years since then, and still no EHCI upstream...

OK, to keep this heavy ball rolling, I would suggest posting your patch.
Either it's already in a good shape to get it merged as experimental
feature. Or I will pick it up in git tree, collect patches as they fly
in, and will keep on pushing it upstream. I can't promise spending much
time on hacking, but integration work, basic testing, and some more or
less helpful comments should be feasible.
