Miscellaneous notes for HP Pavilion laptops
The touchpad does a 'button1' mouse click when you tap it, which is much too easy to do accidentally while typing.
The touchpad isn't supported by the 'synaptics' touchpad driver in xorg, at least with the default kernel (as of 2.6.12).
Looking in /proc/bus/input/devices shows
I: Bus=0011 Vendor=0002 Product=0008 Version=7321 N: Name="AlpsPS/2 ALPS GlidePoint" P: Phys=isa0060/serio4/input0 ...
And the /usr/share/doc/xorg-driver-synaptics/ directory (on Ubuntu) contains a kernel patch to modify the alps support in the kernel.
dmesg(8) also shows
[4315892.898000] alps.c: Enabling hardware tapping [4315892.963000] input: PS/2 Mouse on isa0060/serio4 [4315892.976000] input: AlpsPS/2 ALPS GlidePoint on isa0060/serio4
but there doesn't seem to be any way to disable the hardware tapping.
