I've been progressively disabling the input devices to discover if one
of them may be the culprit via "/lib/udev/rules.d/65-xorg-evdev.rules"
until everything but the GlidePad was disabled:

$ egrep '(Adding input device|PreInit)' /var/log/Xorg.0.log
(II) config/udev: Adding input device "AlpsPS/2 ALPS GlidePoint" (/dev/input/event8)

Using the GlidePad I clicked on the user-name to log-in, then began
typing the password ("my2pennies4"). No password input markers show up
(since the keyboard is not driven by evdev) *BUT* as soon as I press the
"2" xserver crashes.

This seems to confirm that *something* is attached to tty7 and is
processing the input instead of evdev - and then quitting (the SIGQUIT
[signal 3] reports seem to confirm that).

This is the hacked udev rules file used at this point.
