[PATCH] make psaux reconnect adjustable

Hi Linus Alan,

working on notebooks I got used to the touchpads.
Now, a lot of notebooks have a Synaptics touchpad.
It offers a few additional features, such as tossing or the third mouse
button (by a short click in the corner) ...

gpm -t synps2 does support those additional features and via the -R epeater
mode you also get it under X11.

Unfortunately, the synps2 generates nonstandard codes when in extended mode,
amongst which the reconnect (170) token.
The kernel (since 2.2.15) does interpret it as such and empties the queue.

This seems to appropriate for a real plug event. For a synps2, it's not, but
makes your mouse dead for a second. Instead the data should just be passed
to userspace (gpm).

So I made the behaviour switchable via a sysctl.
/proc/sys/dev/ps2/psmouse_reconnect (defaults to 1 = the interpret behaviour)
Being at it, I also made the kbd error and unknown scancode reporting
switchable. (It used to be ifdefs.)

Please apply attached patch (against 2.4.7).

Allesandro, should I submit a patch for gpm to automatically handle this for
synps2 in case the kernel patch gets accepted?

Regards,
