My Antec Fusion v2 case comes packed with an iMon IR receiver & lcd display

When I use ir-keytable like this:
ir-keytable -t -p RC-6
Together with my Windows MCE remote it actually works.
When I use the original iMon pad remote it does absolutely *nothing*

No input whatsoever. Even cat-ing the /dev/input... files does nothing.

I can't set the protocol to "other" or "imon", I get this error:
# ir-keytable -p other -t
Invalid parameter(s)
ir-keytable: -p: (PROGRAM ERROR) Option should have been recognized!?
Try `ir-keytable --help' or `ir-keytable --usage' for more information.
And yes, the original remote still works.

Does anyone know what the problem could be?
