2.5 input drivers Synaptics touchpad

Hi Vojtech,

I just tried 2.5.40 and could not get the Synaptics touchpad on an Acer Travelmate 353 to work with either the synaptics driver for XFree at http://www.mobilix.org/software/synaptics/ or tpconfig at
http://www.compass.com/synaptics/ gpm also does not like the synps2 protocol. Works as (im)ps/2 though.

I have tried with and without CONFIG_INPUT_MOUSE and CONFIG_MOUSE_PS2 using /dev/psaux and /dev/input/mice.

Below is the debug output of tpconfig on 2.4.18 with the 2.5.40 differences on the right:

Hi Vojtech,

Yes, for 2.5 I still have to write a synaptics touchpad kernel driver for it to work properly.

is there any kind of 'raw' psaux interface to those userspace drivers? looks to me as a, at least stopgap, solution. With the disclamer that I know nothing about the interface or the kernel, but i've read the mantra 'userspace' many times (for values of userspace as in X and gpm).
