This actually makes us slightly slower, due to increased register pressure, but I think if I can alleviate that we'll see a speedup.

Woo!

This reverts commit 05116f49.

Blah, this increased our delay from 1ms to 1.2ms. Not sure why it seemed to help at first.

This was just for testing, and now it's getting in the way.

This was included in TeensyDuino, but originally wasn't used.

Almost fast enough.. just 1.3ms more to shave off per frame.

Thanks, OpenMoko!

Removes printf and malloc!

Originally I wasn't planning on doing this, but since I need to reclaim some RAM anyway, might as well just start hacking out everything we don't need...
