Resume from ACPI S3 suspend breaks trackpad, mouse

[Michael Chan]

System: Dell Latitude D600.  After doing (as root):

echo 3 > /proc/acpi/sleep

The laptop successfully enters S3 sleep.  Upon resuming, the trackpad
and pointer are not recognized/not responsive; otherwise resume is
successful including restoration of windowing environment, keyboard,
network modules.  Trackpad/pointer are not responsive at console after
killing X.  This situation persists across a warm restart; a shutdown is
necessary to re-discover the devices.
