Comment 4 for bug 666493

I managed to get this to work with the maverick kernel by catting "rc6" rather than "rc-6" to /sys/class/rc/rc0/protocols.
e.g.
    echo rc6 | sudo tee /sys/class/rc/rc0/protocols

This combined with

    sudo ir-keytable -p rc6 -w /etc/rc_keymaps/imon_mce

Got it working for me.

I put this in rc.local for now, but there is a chance the modules may not have loaded when rc.local is run, so I've forced a modprobe for now. Once this is all in udev it should be much cleaner.
My rc.local looks like this:

modprobe imon
ir-keytable -p rc6 -w /etc/rc_keymaps/imon_mce
echo rc6 > /sys/class/rc/rc0/protocols
