I tried booting NetBSD, which seems more or less successful, so long as I don't try installing to a hard drive (or anything else beyond navigating directories and running dmesg), in which case it freezes hard (no kernel panic or anything).

Nothing that I understand seems to be wrong in dmesg except the last two lines:

That warning appears regardless of the date/time settings in Mac OS X.

And why would it be off by 42 days?

By the way, it successfully initialized the RTC.

I'm stumped!

EDIT: While was typing this post, I noticed that it had frozen solid while idling.
