The problem with X.org segfault-ing boiled down to an issue with the X
Server calling vfscanf(3) in a funky way, which happened to be fixed
by r234836.

Also, the issue with NV-GLX has been fixed by some update (maybe the
new NVIDIA driver?), so that's cool.

I continue to battle with my trackpad, as after exiting X the new
synaptic driver doesn't seem to let go of /dev/psm0 -- I'll start a
new thread for that after further diagnosis.
