I upgraded my ac100-10D from 11.10 armel to 12.04 armel and although 
everything seems much better now, also lost my trackpad, it just doesn't 
work. USB mouse is fine.

My kernel is 3.0.19-2-ac100, here is the result of 'cat 
/var/log/kern.log | grep nvec':
Apr  2 20:10:33 lflores-laptop kernel: [    1.351845] nvec nvec.0: using 
adapter Tegra I2C adapter.2

device: nvec-led

It seems the trackpad is not detected, in /sys/devices/virtual/input/ 
there is
[input1 input2 input3 input4 mice] (without USB mouse connected), but 
input[1-4]/name is:
nvec keyboard
nvec sleep button
nvec power button
nvec lid switch button

mice dir only has a dev entry with 13:63

Thx,

Luis Flores
