[PATCH] Alps touchpad probing failure

Hi,

 With 2.6.11-rc1 bk6 and bk7 (didn't tried with < bk6), my alps touchpad is no 
more correctly probed, it's recognised as a standard PS/2 mouse.
 So, with this trivial two line patch, everything is working again.

Cheers.

Hi,

I think Peter Osterlund has send similar patch recently - the breakage
appears to be caused by Kensington mouse detection. It looks like these
two don't like each other.

 Oh, i see. Okay, maybe that explain why the ps2 command _CMD_GETINFO returned 
the wrong 0x0 0x0 0x16 values.
