[2.6.30-git17] Touchpad stops working after suspend to disk

[Maciej Rutecki <maciej.rutecki@gmail.com>]

Tested kernel: 2.6.30-git17
Last known good: 2.6.30

To suspend to disk I use 2 methods, kpowersawe or this script:

#!/bin/sh
governor0=`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor`
governor1=`cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor`
f_min_0=`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq`
f_min_1=`cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq`
f_max_0=`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq`
f_max_1=`cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq`
/sbin/rmmod iwl3945
/sbin/rmmod mac80211
chvt 1
sync
umount /mnt/windows
sleep 1
echo platform > /sys/power/disk
echo -n disk > /sys/power/state
mount /mnt/windows
echo $governor0 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo $governor1 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo $f_min_0 >  /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo $f_min_1 >  /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq
echo $f_max_0 >  /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo $f_max_1 >  /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
/sbin/modprobe mac80211
/sbin/modprobe iwl3945
chvt 1
chvt 7
sleep 5
/etc/init.d/laptop-mode restart
hdparm -B254 /dev/sda

For both resume works without touchpad. I must manualy do:
rmmod psmouse
modprobe psmouse

then works.

How debug it?
