Yes, I will. I'll submit it to the lirc people as soon as I have done 
some more testing and the autorepeat issues are solved.
I don't like submitting a piece of code that won't work.

No, there is no problem at all! 
The point is that the key-up event is not  generated *before* I release 
the key. Therfore the hauppauge remote control works perfectly with the
