This is a very interesting project indeed. I would love to use bootx, if it would provide better hw support than mol. Usable, working sound and 3d is really missing at the moment, and it's not so comfortable to boot linux kernel and mol every time you want to use osx (even if it's a molk or pegxmac). The overall osx speed feels much slower compared to g4 macs, as without 3d support the gui is quite slow.

Let us know any news about BootX. How is it going? ;)
