I have been switching to the vty at which I started X in order to
terminate X. If I try to terminate X while I'm in it, it just "hangs"
-- I have to switch to the vty, ctrl-c it, wait, then blindly key in a
reboot to get my system back up. IIRC, this started happening after I
upgraded to Xorg 7.4.

I thought that Mattia might be doing the same thing as a work-around
for the freezing intel-driven display thing, thus the X-to-vty switch
"fix" of disabling msi...
