Hi. I'd like to clarify one thing. The "Macintosh mouse button
emulation" driver is loaded and recognized on all hardware whether you
have it or not. It's a generic driver.

Can someone confirm that what @ndde says is true? Meaning, does the
2.6.30-8-generic kernel detect the touchpad as ALPS and further more,
does it work correctly and can the Gnome Touchpad Configuration
utility set up the touchpad (scrolling areas, tap to click, that sort
of stuff).

And yes, anything before 2.6.32 still uses HAL. HAL was removed in
Lucid Lynx, so whatever kernel Lucid came out with, that isn't using
HAL anymore, it's using DeviceKit.

That leads me to believe that DeviceKit scripts aren't detecting the
touchpad correctly. The drivers are there, it's just not loaded.
So, now someone needs to hack DeviceKit on Lucid to load the
appropriate driver. Which driver? Dunno, check what Jaunty is loading
(thank you VirtualBox).

I myself don't have time to test this because I came up with this idea
a moment ago and I'm at work all day.

Good luck.

BTW, I have a Sony Vaio VPC-EB1S1E White Model (Ie. /Wi.EE9) which
most likely has an ALPS touchpad (all the symptoms are there).

And the kernel is not detecting the ALPS touchpad and the cat /proc/bus/input/devices says it is a  PS2 mouse ..
