Correct, just a typo, not the cause of the problem.

A rebuild of the kernel without atp didn't solve the problem:
powerbook# kldload atp
powerbook# ls /dev/atp*
ls: No match.
powerbook#
The attach error messages have gone but there's no atp node.

The next step I tried, was a rebuild of the whole system. Therefore I
updated my source tree with csup to RELENG_9_0. I now have this on my
PowerBook: "FreeBSD 9.0-RELEASE-p1 #3: Mon May 28 21:49:45 CEST 2012". I
tried a kernel with and without atp but the touchpad still doesn't work.
