Right, so really more of an issue on our side having kernel/loader functionality catch up to what the hardware should be capable of. > It's been said several times on this list that running an amd64 as > an i386 works quite well and _is_ really fast. I can't confirm that, > though. 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. > SATA seems to be the primary source of woe on this list right now. > Check the archives a little.

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.
