Yes, Fedora too has had the IR drivers move into the kernel, so it
will be using ir-keytable (or some equivalent software).

So what driver does your IR receiver use?  Can you see it loading in
the log files?  In Mythbuntu, that would be in dmesg or kern.log, but
I have no idea how Fedora does its log files these days.

You mentioned doing:

  modprobe lirc_serial

When you do that, if lirc_serial is the driver, then you should see
new lines in the log files saying what device the lirc_serial driver
created.

Or if lirc_serial is loading already at boot time, the log lines from
it may be hard to find, so if your IR receiver is a USB one, just
unplug it and plug it in again to get it to log what it does again. If
it is not a USB device, you can get the same effect by unloading and
reloading the driver:

  modprobe -r lirc_serial
  modprobe lirc_serial
