[Bishnu Bidari]

Actually i find out that we have two set os SKU320 one with Synaptic touch
pad and other with Sentelic. And the Sentelic one is not working. And this
SKU326 have Sentelic touch pad.

yes my SKU320 respond with "test /mouse"


i followed instruction on
http://wiki.laptop.org/go/OS_Builder/Enable_taptoclick but noticed no
change.


SKU320 with synaptic result no output( which is working)
bash-4.2# dmesg | egrep 'psmouse|serio1'
bash-4.2# /usr/bin/olpc-fsp-regs verify
bash-4.2# olpc-fsp-fwread
