device nodes seem to be missing

Binary package hint: xserver-xorg-input-synaptics

After upgrade from Jaunty to Karmic the touchpad on Packard Bell stopped working. Kernel module is still loaded because I can cat /dev/psaux.

Problem seems related to udev/evdev. Error received from Xorg.0.log

Problem only occurs on 2.6.28-15 kernel. When using the latest 2.6.31-11 the problem is resolved.
