Probably.

Vojtech and I designed the ff API so that it's not I-Force specific. We
may need to add/change some parts of the API, but what the ff_effect
struct is supposed to be generic enough to be used with other kinds of
devices. Have a look at input.h. Nothing in it should be I-Force specific.
Now, it's true there are parts that could be re-used or adapted from
iforce.c (the parameter blocks allocation and handling, for example).
