Some fixes for PS/2 mice:

- fixed hotplugging (real reset of device instead of softreset)
- support for Targus Scroller mice (from my last weeks patch)
- extended protocol probing fixed

The major change is that the probing of extended protocols is now changed to 
be more configurable. Previously the driver probed for all the protocols it 
knew about and stopped when it found one that the mouse accepted. This didn't 
work with a bunch of mice so now you can choose the protocols which are to be 
probed.

In current 2.6.5 the parameter "proto=imps" probes all protocols up to ImPS/2. 
The patch changes this so that "proto=imps" ONLY probes for ImPS/2 and if 
that fails uses regular PS/2. Similarly "proto=ps2pp,genps,exps" probes for 
Logitech, Genius and Intellimouse Expolorer and if none found uses the bare 
PS/2.

To be continued.....
