I'm also having this problem with an HP Pavillion DM3 that I bought today - I had to create a /etc/modprobe.d/psmouse.conf file with "options psmouse proto-imps" in order to get edge-scrolling working.
The issue appears to be caused by the touchpad being incorrectly detected as a PS/2 mouse. When I do the following:
xinput test "AlpsPS/2 ALPS GlidePoint"
nothing is registered. When I do this:
xinput test "PS/2 Mouse"
I get co-ordinates for every movement of the trackpad.
Currently on Ubuntu 10.04 64-bit, kernel 2.6.32-22-generic.
