Hmm, what kernel are you using? the binary on Ben's page or a selfcompiled
one? Old mode (kernel_sends_linux_keycodes==0) or new mode
(kernel_sends_linux_keycodes==0)?

The Fn key is not really handled right now and probably requires more kernel
support for the key combos not handled in HW. Anyone has a list of these
combos?
