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?
