I'm running XUbuntu Gutsy (7.10).

I managed to find a way around the dual keypress issue, but it's a real hack.

In the lircd.conf file, there's a toggle_bit setting that seems to mark the 
difference between a key press and a key release. If you 'and' the inverse of 
this mask with the key scan codes, you won't be able to tell the difference 
between a key press and a key release.

So, by setting the toggle_bit value to something outside of the key scan code 
range, the key press and the key release scan codes become different.
