which probably means there is either something happening that
our hardware driver doesn't cover, or there is a hardware/firmware
bug. Anyhow, it's strange because the drivers only need very
basic data to identify a tap: the start of a contact, its
end, and the duration. Have you checked - with the synaptics
driver - whether a higher tap timeout helps? If not, would you
mind to make a short test? Could you increase the tap timeout
to a very high value, say, two seconds, and test whether a tap
works (with a slight delay)? For the wsmouse-internal driver,
the following command will set a two-second timeout:
# wsconsctl mouse.tp.param=137:2000
Of course you could not work reasonably with such a timeout,
you might want to check then whether something between 200
350 milliseconds would do. The default is 180.

Does this also work if you put a second finger on the touchpad (which
does nothing)?
