(Yeah, I'm confident that I booted these different versions; I installed and reconfigured grub and booted them as soon as I saw them in portage just in case they had fixed a bug I was hitting.)

This actually seems to have helped. When I switched over to the vanilla sources, I was able to use the machine for a lot longer than usual before something bad happened, and the new problem seems unrelated to the mouse/keyboard. At least, the machine is locking up completely, not just the mouse or keyboard, which I guess is progress? 

I'll probably be back later for help on that one.
