Hmmm, I am concerned about the lines that say...

empeg:/sbin# ro
mount: / is busy

Something is running from the drives and it did not properly mount them read only. This may mean that the files you added (ir init, and ir map file) never got written out to disk. Connect to the empeg again and make sure they are actually there. Also, post a full boot log (connect with terminal program and then plug in empeg power). IIRC frank's stuff prints out all of the remappings when the empeg boots.

You may want to just try adding the files again to see if you can get it to work without that error.
