This may or may not be helpful, so my apologies if I'm up the wrong
tree. I'm not sure if the CF-R{8,9} share the same touchpad.
I have a CF-19k and my Synaptics pad was never recognised as such, so a
while ago I attempted to hack the psm(4) code to force it. I was able
to force it and change from abs to relative (or maybe the other way,
I forget), but when I did I had similar problems with a cursor moving at
random.
Is your touchpad a Fujitsu touchscreen/touchpad (FJC6001 - I think) like
the CF19? If so I believe Linux have a Fujitsu Lifebook
touchscreen/touchpad driver that treats the device as two different
units, touchpad & touchscreen (I believe the hardware appears only as
one device but has two outputs). Unfortunately, the touchpad side of
things appears to be a plain ps/2 device without Synaptics
capabilities (the hardware/programming spec was out on the Internet at
some point). However, with very minimal effort I think the touchscreen
could be enabled via psm(4). I have not been able to try it as my CF19
has the Wacom touchscreen (which doesn't work on CURRENT :( ), but it
still retains the full Fujitsu touchscreen/touchpad device.
HTH, if not good luck and sorry for the wasted bandwidth.
