    Right, so really more of an issue on our side having kernel/loader
functionality catch up to what the hardware should be capable of.

    That's great... I don't *need* a 64-bit environment right now, but
I figured since I'm dropping the cash on a system like this, I better
buy something that'll last me a few years... okay, i386 it is then, at
least for now.

    Soren committed a 3114-related patch to the atapci stuff very
recently (like less than 2 weeks ago, I think), so I'll have to
investigate that.  I suppose at the very least, I can hook up any old
IDE drive, install/boot from that, then look at getting the SATA stuff
working.  Thanks for your comments.
