Every receiver module I've seen (a handful salvaged from equipment, plus the
packaged one sold by RadioShack in the US) has been active-low, rather than
active-high.

Assuming you've build the serial port circuit, I've noticed lirc_serial will
default to active-high if you load the kernel module with nothing connected
to the port it's watching.  So, you might have a wiring problem, maybe
reversed +Vcc and signal-out pins?  Or lirc_serial could be watching the
wrong port.
