If I'm thinking clearly, there are only three lirc kernel drivers that support transmit, lirc_mceusb, lirc_zilog and lirc_serial. The mceusb driver was posted, so I won't rehash what it is here. The zilog driver binds to a Zilog z80 microprocessor thingy (iirc) exposed via i2c, found on many Hauppauge v4l/dvb devices (PVR-150, HVR-1600, HD-PVR, etc). The serial driver is fairly self-explanatory as well.

There are also a few userspace-driven devices that do transmit, but I'm assuming they're (currently) irrelevant to this discussion.
