Jason: I'm pretty sure that this is a limitation of the synaptics driver
in X for semi-multitouch devices, and not a problem with the kernel
driver. Could you please do the following to help verify this?

Make sure you are booted into the oneiric kernel and that you have the
input-utils package installed (sudo apt-get install input-utils). Switch
to a virtual terminal by pressing Ctrl-Alt-F1 and log in. Run 'sudo
lsinput' and identify the event device number for the touchpad in the
output. Then run 'sudo input_events dev_nr > input-events-oneiric.txt',
substituting the device number you identified in the lsinput output for
dev_nr. While input-events is running, do a few 3-finger taps. Press
Ctrl-C to cancel input-events, then press Ctrl-Alt-F7 to switch back to
the desktop. Reboot to the natty kernel and repeat, changing the output
file name to input-events-natty.txt. Attach the input-events-*.txt files
to this bug.

Thanks!
