does not contain button information.

From Alastair M. Robinson:
* The guest mouse doesn't report button releases.
* The stick pointer has buttons of its own, and they don't work.
Attached is another patch, this one far less invasive than the last,
which fixes these two problems.
(The button presses that come from the stick pointer's buttons arrive
in events with pressure set to 127, just like stick movement - but
this doesn't seem to be terribly reliable - I think the button
release gets reported with true pressure when the touchpad is being
used too. For this reason, I've set these up to report as ->left /
->right, not as ->guest_left / ->guest_right.)
* One issue that remains - the middle button emulation for two button
mice doesn't seem to work for the guest mouse.
Fixed by me.

dualpoint stick packet is received.

<blackfive@fakenhamweb.co.uk> to make the ALPS dual trackpad found on
Dell CPx machines work. (For 2.4 kernels.)
In order to get my trackpad working in absolute mode I had to make some
modifications to the driver:
Firstly, initialising the trackpad on this model is more complicated
than other ALPS devices; the usual "magic knock" must be performed for
both the trackpad and the pointing device, and I found that I needed a
device reset first to get reliable initialisation.
Secondly, the pointing stick, for obvious reasons, provides relative
data even when the trackpad is in absolute mode.
Thirdly, the guest mouse in the PS/2 port continues to send 3-byte
packets.
