J820 trackpad driver

[G Almasi]

I have added the trackpad driver to the kernel. I tested
it with gpm (note that there is no gpm on the initial ramdisk,
you have to install it yourself). The driver itself is
in j820_keyb.c - this seems to be the usual way it's done.

gpm -m /dev/psaux -t ps2

Question - where should we keep the technical
documentation? all the golden tidbits of reverse-engineered
knowledge that were gathered by Oleg should be kept somewhere,
probably organized by devices. Ideas?
