Yes.

Personally, I think you're going about it wrong. For one,
lirc_parallel isn't smp-safe, and won't even compile on an smp system,
so if you have a CONFIG_SMP kernel (which almost all distro kernels
are these days), it won't work. I'd just get an mceusb transceiver,
which has dual blaster ports on it (you set the blaster tx mask based
on which ports you want to tx on), and will only set you back $20-30,
and works out of the box without manual module probing, etc.

Oh, and say hi to Jarom for me. :)
