Interesting.. I assumed since evbug was not producing usable codes for
these keys then the evdev layer would not get any codes at all.

Starting from what version did this ioctl get added and is it documented
anywhere ?

Nevertheless the patch you sent got the "TXT" key to work but not the
"BACK" key. Here are the codes for all of the non-functioning keys
( TXT , BACK , 4 COLOR keys ):
