Try changing PACKET_SIZE (originally 256) in lircd and recompile.

If I understand correctly, the PACKET_SIZE is the size of the transmit 
buffer; using pulse-width-modulation

exactly two entries are needed for each bit (on-period and off-period), 
so is appears to fit the scheme with Lircd (NOT irsend) misbehaving for 
<= 128 bit payload.
