Hello,

It does indeed get listed as SynPS/2 Synaptics TouchPad after setting that
loader tunable. I thouht those  hw.psm.(synaptics|elantech)_support was
just for basic touchpad stuff for sysmouse.

However xorg still wont play: synaptics: SynPS/2 Synaptics TouchPad:
Synaptics driver unable to detect protocol.

Thanks for helping me getting this far!

Best regards
