Have you verified that /dev/lirc/0 is created after you load the driver?
Assuming that /dev/lirc/0 is the correct device file, are you specifying
this to lircd when you test it? By default, lircd assumes that it should
connect to /dev/lirc to talk to the device driver. If /dev/lirc/0 is the
correct device file, you will need to specify '--device=/dev/lirc/0' on
the lircd command line when it is started in order to tell it the correct
file to open.

What about the serial driver in the kernel? Are you making sure to either
not load the serial port driver, or to use setserial to set the uart to
none so that the kernel won't fight with lirc over the serial port?

I wouldn't assume a hardware problem yet. It still sounds like you may
have configuration issues.
