Except that I don't get yelled at by so many people when things break.
Why do you think I work on powerpc? (/s, kind of).

At least it's a reference, hopefully we can get a bit more interest. If
we get a few converted then we could find some common patterns and pull
them into generic code or at least a simpler recipe as we try to convert
everything and just make this the only way it's implemented. Of course
we need the big archs on board at some point.

Thanks Matt, I'll put a git tree up and ping you.
