I have a similar problem with the touchpad being detected as "ImPS/2 Generic Wheel Mouse" (looking at /proc/bus/input/devices).

The effect is that I cannot configure it and in KDE, the touchpad configurator is greyed out - the problem is described in bug 584999.

I'm not sure whether my device is Elan or not - how can I verify it?

My machine is a Sony Vaio VPCEB1M1E laptop:

# dmidecode -t System
# dmidecode 2.9
SMBIOS 2.6 present.

I've tried the patches mentioned here by performing the procedure from http://ubuntuforums.org/showthread.php?p=9175201#post9175201 on kernel 2.6.32-23-generic. They did not resolve the problem.

For the record, the patches I've applied against kernel source before rebuilding psmouse module were:
