Yesterday right after I installed Unbuntu Linux (version 2.6.35-22 #33-Ubuntu) on my new Dell M4500, the touchpad worked fine -- I set up vertical and horizontal scrolling and left-edge zooming. But after a reboot (or maybe the updates), the touchpad is no longer recognized, with the exact symptoms detailed above. The current version after the updates is 2.6.35-27-generic-pae #48-Ubuntu. I note that the touchpad is now not recognized by 2.6.35-22 when I boot to my CD. I didn't try a re-install.

Same symptoms on clausoft MNW737 "meenee" netbook, running 10.10 Natty, also Beta 11.04

I wonder if a patch to psmouse.ko as suggested (for non-detection of an ALPS touchpad) in https://bugs.launchpad.net/ubuntu/+source/linux-meta/+bug/754344 would do the trick?

Because the touchpad is not recognised as such, I can't disable tap-to-click or adjust the sensitivity.
