You need no modulation, not hardware PWM modulation. That driver solves 
a problem that is not relevant for you. It appears not to "frequency 0" 
capable. If you want to us that one, you have to ask its author for 
support.

Setting softcarrier=0 MIGHT work as alternative to FREQUENCY 0 in 
lircd.conf. Look in the system log for messages.

You are using the latest (upstream) Lirc?
