Yes, that seems to work.  I can use the USBasp with that.

I've also been able to test your original bitbang patch with my "bsd"
programmer (Brian S. Dean's original parallel-port bitbang dongle).
Works fine as well.

No idea why my "ponyser" dongle currently doesn't want to handle TPI
at all (even though ISP works), but I wouldn't care too much for that.

I'd say, go ahead and commit them.
