No touchpad on pavilion dv2899 laptop

[David DEMELIER <demelier.david%gmail.com@localhost>]

Hi,

I posted a PR for my touchpad on my laptop (kern/41533)

The touchpad is just identified as a simple mouse (I can use it but no
hw.synaptics sysctl variables exists).

pms0 at pckbc1 (aux slot).

And there is

options         PMS_SYNAPTICS_TOUCHPAD  # Enable support for Synaptics Touchpads

In my kernel config file. It's not so serious (it works as I said I
can use it but I can't set the scroll for exemple).

Cheers, David
