Do you have the appropriate FF module built and loading in your kernel,
it
was recently moved to be enabled with 'LOGIWHEELS_FF' and is supported
by
the code in 'drivers/hid/hid-lg4ff.c'

And also, I don't have "hid-lg4ff.c" in this
"linux-dopx:/usr/src/linux-2.6.34-12/drivers/hid" path. I have
"hid-lg3ff.c" etc.
Is it responsible for the force feedback not working in the native mode?
Will I have to compile the kernel or something? :( :(

Ah, or simply download that file and put its name in the respective
Makefile? Not sure.

If you don't have it then it is probably easiest grabbing a more recent
pre-built kernel from your distribution. I suspect that SuSE has somewhere
for getting 'leading edge' kernels.

'hid-lg4ff' was improved by Michal back in August to include support for
all Logitech wheel and run them in the native mode (to get 900' rotation
etc).

A change log is here:
