Same problem on a Lenovo 3000 N100. I’m running Karmic amd64 but also
saw this in previous versions. i8042.reset=1 didn’t help.
MODULES="psmouse" in /etc/default/acpi-support helped sometimes but not
always. I’m now using this script in /etc/pm/sleep.d/90andersk-i8042,
and the problem seems to have gone away:
#!/bin/sh
case "$1" in
hibernate|suspend)
modprobe -r psmouse
echo -n i8042 > /sys/bus/platform/drivers/i8042/unbind
;;
thaw|resume)
echo -n i8042 > /sys/bus/platform/drivers/i8042/bind
modprobe psmouse
;;
esac

Synaptics touchpad ceases functioning after suspend and resume.
