I have all those except type, softcarrier txsense and debug. I tried
various combinations on the commandline of those, but I tried so many
that I can't remember if I did those at the same time. I'll stick
those in and try it.

I think I'm fine:

 # ls -lsa /dev/lir*
0 lrwxrwxrwx 1 root root     5 May 13 08:55 /dev/lirc -> lirc0
0 crw-rw---- 1 root root 61, 0 May 13 08:55 /dev/lirc0
0 srw-rw-rw- 1 root root     0 May 13 16:56 /dev/lircd

At one point I chmod'd these to 777 just to check.

Thanks for your help!
