Lets look at this as a configuration problem. I mean, after applying the
psmouse patch, and the system sees the device, how can we control it?
I've got a new Dell Precision M4600 and it has the ALPS touchpad that
other people are struggling with. I've found many bug reports on it on
all of the Linux sites.
I applied the patch, as you described, and after that the touchpad seems
to be recognized as a touchpad. Commands like "synclient -l" do
recognize the device and print out settings. However, changing the
parameters with synclient has no discernible effect, and I'm uncertain
whether this means
the synclient commands are having no effect, or
the gnome operating system is fighting with me for control of the
touchpad.
Or, possibly,
even though the system seems to see it has a touchpad, this particular
touchpad is still controlled as a mouse. Watch what happens if you go into the
mouse controller in gnome, and in the "newly revealed" touchpad control area,
you turn off the options like "click to tap". Even after that, the click to tap
still works.

And more good news:
I know for sure the patch makes a difference, since this output is definitely
different and encouraging
$ cat /proc/bus/input/devices

Before the patch, I was getting the "no device or driver" error from
synclient, now I get this, however, changing the settings has no effect
on behavior of the touchpad.
