With the latest changes in driver for Sentelic touchpad I’m eventually able to use two-finger scrolling, and disable touchpad while typing.
Middle-button emulation and on pad click & drag doesn’t work yet, though. Edge scrolling either.
Anyway it starts to be really usable and there is some progress to merge this driver with mainline kernel.
I believe last time I was compiling kernel was around 2.4.18 and only because at that time I was maintaining router for some network and needed some special iptables extensions. Happily it hasn’t changed too much since then and I can compile 3.2.1 without problem
