First sorry Thomas, it was my fault with ACPI video, i habe at this
moemnt to many different modules of that for testing and used the wrong
one at time of writing the e-mail yesterday. :) It is correct now and
looks like:

babyface@bart:~$ dmesg | grep video -i
Boot video device is 0000:00:02.0
input: Video Bus as /devices/virtual/input/input3
ACPI: Video Device [VID] (multi-head: yes  rom: no  post: no)
ACPI: Video device VID not physically connected, ignoring

This will fix the issue with multiple VID devices in /proc but the rest
will still occur, of course this is no fault of ACPI video. X.org will
still show:

(II) Primary Device is: PCI 00:02:0
(WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found
(--) Chipset 965GM found

Notebook is a X61 tablet and the latest bios would be 1.06, but i had not
enough time to upgrade it. With dmidecode i was not able to find a string
called KEWWT456.
