Ok, I figured this out, as it turns out I was using the wrong keymap for
the way my remote was programmed, I needed imon_mce and not rc6_mce. I
got the two files mixed up in my head and was looking in one when I
thought I was looking in the other. Sorry. Its all working now (though
the crash there was a little odd).
