As I said previously, you should look into not making that a config
option but rather a runtime option.

I know, i've also quoted your mail in the readme file as a reminder.
This is only an update written in a couple of minutes because i've
updated the kernel on my ibook.

I haven't much time to spend on this patch now, so i haven't still found
a good solution; i've only studied a little sysfs and kobjects.
I'd like really much to receive some ideas and suggestions!

thanks

luca

Can the driver be informed when synaptics takes control of it btw ?

Not currently.

On x86 absolute mode is set on psmouse-base module initialization.
There's no config option here, if you build the kernel with psmouse and
you have a synaptics touchpad you can use it only in absolute mode
(mousedev takes care of a proper absolute to relative conversion).

X driver opens event interface and check for ABS_X, ABS_Y, ABS_PRESSURE
and BTN_TOOL_FINGER bits with an ioctl. If success it hooks the device
with another ioctl to evdev.

Maybe it's time to suggest adding a specific one for switching..

Ok, i've contacted Peter Osterlund, the author of synaptics support in
kernelspace and userspace. Waiting for its reply.
