[synaptics] Configure clickpad right button

[Bjoern Olausson]

Hej all,

just wanted to let you know that I could solve the problem with abolute 
values:

# "RBL RBR RBT RBB MBL MBR MBT MBB"
Option "SoftButtonAreas" "0   0   4300   0   0   0   0   0"

Now I just have to play a bit with "FingerLow", "FingerHigh" and the vertical 
scroll speed.

Thanks for your support.

Cheers,
Bjoern
