Again, what initscript are you using to start lircd? The Fedora lirc
initscript does NOT use hardware.conf -- that's a Debian/Ubuntu thing.

And also again, why aren't you just using the Fedora lirc packages?
They're known to work just fine with the current Fedora kernel.

And you probably still don't have lirc_i2c binding to the card at all,
which means it doesn't matter *what* lirc userspace you install. :)

Is this by chance a PVR-150 with both RX and TX capabilities? If so,
look into lirc_zilog instead.

Take 'rhgb quiet' off the kernel boot line and add 'debug'. There's
also some i2c bus poking you can do. But I'm guessing the primary
issue is that you need lirc_zilog instead of lirc_i2c. Each i2c part
these days must export a device name to the i2c subsystem, and drivers
will only bind to that device if its name is matched in the driver's
list. Some PVR-150, which have RX only, have the generic 'ir_video'
(iirc) exported, which lirc_i2c will bind to, while others have a more
specific export which I don't recall offhand, but its only matched by
the lirc_zilog driver.
