What sort of machine is this and what device is the console?  The cnmagic 
code only works on the console input device if that device has the cnmagic 
support hooks.

wskbd.c currently does not support cnmagic.  Someone should probably add 
that.  OTOH, someone should also change wscons so we don't translate from 
USB keycodes to whatever we're using internally to what the X server 
expects.  It's redundant and really complicates things like adding cnmagic 
support.
