Weird thing about this is, "lshal" clearly shows the attached PS/2
keyboard and mouse input devices. Yet, the X11 "evdev" driver either
isn't getting loaded, or doesn't see the input devices. Looking in the
/dev/input/by-path directory, I see the expected symlinks for
platform-i8042-serio-0-event-kbd --> ../event0
platform-i8042-serio-1-event-mouse --> ../event1
platform-i8042-serio-1-mouse --> ../mouse0
platform-pcspkr-event-spkr --> ../event2
Tried getting rid of xorg.conf entirely. Discovered existence of
/usr/share/X11/xorg.conf.d and all the files it contains by default.
No difference as far as getting a working keyboard and mouse. So, I
whipped out the "nuclear" option:
Option "AutoAddDevices" "false"
This allowed the standard "kbd" and "mouse" drivers to load, and I now
have a working Xserver.
Dunno... Something in the hal <--> dbus <--> udev chain might be broken,
or maybe the mechanism Xserver uses to access what hal knows about isn't
quite right. Regardless, the workaround enables the desired/expected
