is a full dmesg available somewhere (after the resume from ram and after
re-inserting psmouse)?

yeah, and I suppose the touchpad doesn't show-up in
/proc/bus/input/devices, right?

create the device you have no chance to make it work simply creating the

If all the above is correct, I'd say this is a kernel problem and you'd
better report it to the correct people[1] (maybe after trying the latest
and greatest kernel in the hope it's already fixed).
