[PATCH] ALPS: fix enabling hardware tapping

[Dmitry Torokhov <dtor_core@ameritech.net>]

Hi Linus, Vojtech,

It looks like logic for enabling hardware tapping in ALPS driver was
inverted and we enable it only if it was already enabled by BIOS or
firmware.

I have a confirmation from one user that the patch below fixes the
problem for him and it might be beneficial if we could get it into
2.6.12.

Thanks!

Input: ALPS - try enabling tap mode if it was disabled, not if
       it is already enabled.
