FYI; the Power/Power2/Power3 processors are IBM engineered. Not Motorola
engineered. Or at least that's how it was explained to me. They're PowerPC
based, though. Yes, it's confusing. If somebody can get me actual specs
on the Power processors, and/or a machine to test with, it'd be much
appreciated. Just, umm, hold off a bit. I'm kinda busy for a few more
weeks. Ugh.
