Hi, in order to get the Synaptecs config utility to work, i had to apply
the
following path (not mine - see original post).
http://www.uwsg.indiana.edu/hypermail/linux/kernel/9904.3/0887.html
the same patch against 2.2.13 is attached (sorry for stripping down
original comments - had to apply it by hand).
Cheers, Dmitry
