Under Ubuntu 6.06 (Dapper Drake) on my Toshiba Pro M50 I have a working Alps touchpad, and here are some clips which might help.
dmesg shows ... [17179575.564000] mice: PS/2 mouse device common for all mice

lsmod includes psmouse 36100 0
xorg.conf has ( IIRC I had to change this to /dev/input/mice from /dev/input/mouse1 to enable both USB mouse and touchpad, but I'm a bit foggy here!)

within the GUI System->Admin->Device Manager I have the following settings for the Alps glidepad ( it shows it on the Aux-3 port on Platform Device (i8042) similar to the keyboard) input.device /dev/input/event3 linux.device_file /dev/input/event3
It would appear that mine does not use PS2 nor USB but the chipset i8042 for the keyboard and "mouse"
I hope this helps a bit. Keith
