To write xf86-input-evdev's abs support, I ended up with a touchpad that uses the kbtab driver, sadly, it needed a few tweaks to be usable.
We should report the touch event, actually needed to get accurate data.
We should not report a middle button that we don't _have_, it doesn't
help anyone to do so.
And we should always send pressure data, even when we're generating
BTN_LEFT from it.

The story includes this array of huge rhymes-with-hell machines, all running
screensavers, the power and SAN cables neatly run between them... and the
disused tape-storage closet stuffed with old Sun boxen still humming quietly
away. - adb in ASR on rumours of a flawless SunOS to NT site cutover.
