I found out at least why this happens. The EFI BIOS has a setting for "USB Legacy mode" for the pointing device. If I enable it, the touchpad disappears, if I enable it shows.
However, neither enabled nor disabled the touchpad works!
I would assume that in compatibilty mode maybe it shoudl somehow work as a simple mouse?

With compatibility mode, this is reported by xinput:

$ xinput
⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
⎜   ↳ Logitech USB Optical Mouse                  id=10    [slave  pointer  (2)]

    ↳ BRLTTY 6.3 Linux Screen Driver Keyboard     id=14    [slave  keyboard (3)]



And Steve's script does:
sh touchtoggle.sh
diagnostic devid =13
diagnostic scratchline=Device Enabled (175): 1
diagnostic proptext =Device Enabled#
diagnostic propid =175
Current state of 1 has been changed to 0.

and it always says 1->0 even if you rerun it.

More ideas?
