Well, re-running emerge on the driver set had at least two effects. 1) The segfault address moved, and 2) the backtrace moved, 3) the error changed.

Kinda wish I could stay and comb it, but if I don't get into traffic before rush hour, it'll tack a good 30-45 min onto my commute length.  Will have to go through it when I get home!

That, is an interesting question, because I HAVE been changing USE flags. When the kernel was built it had a distinctly different use flag set.   Now it's USE="mmx sse sse2 ssh X -gnome -kde -qt4 dbus jpeg lock session startup-notification thunar udev -cdr -dvd alsa gtk"

I might be giving myself away as a gentoo noob here, but I haven't technically built anything.    When you say, "rebuild" are you referring to basically the same process as emerge?   That's how I got my drivers and xorg, but when I think of building something I always think of configure/make/make install, and I want to be sure I'm not doing the wrong thing because of a misunderstanding

well, it is not a driver issue. Your server segfaults. Have you set strange
flags? have you rebuild xorg-server and all the stuff it depends on with sane
flags?
