Actually, HAL is old hat :-) udev was used next, and now there is a
new "InputClass" syntax for xorg.conf. That gets used for anything not
discovered automagically or nonstandard. It is worth reading the revised
man page for xorg.conf.
I use Logitech trackballs (and have a synaptics pad on this netbook) and
all of these need "InputClass" entries.
