I'm the same, except that I have to Kernel Modules, in addition to 
lirc-kmdl-2.6.11-1.14_FC3-0.7.1-46.rhfc3.at, I also have 
lirc-kmdl-2.6.10-1.770_FC3-0.7.1-46.rhfc3.at

I'm assuming I can skip this step since I'm not worried too much about the 
power button at the moment.

modprobe gave me the following error:
[root at sumo ~]# modprobe lirc_serial
FATAL: Error inserting lirc_serial 
(/lib/modules/2.6.11-1.14_FC3/updates/drivers/lirc/lirc_serial.ko): Device 
or resource busy

Then,
[root at sumo ~]# lircd --pidfile=/var/run/lircd1.pid --device=/dev/lirc1 
--output=/dev/lircd1
lircd 0.7.1: there seems to already be a lircd process with pid 4055
lircd 0.7.1: otherwise delete stale lockfile /var/run/lircd1.pid

And my modprobe.conf file:

Whenever I uncomment the references to char-major-61-0, -1, and the 
assosciated  lines, my remote control stops working.   As it sits now, I 
have a working remote control, just the IR blaster won't work.

Here is the contents of my rc.local script in /etc/rc.d
[root at sumo rc.d]# less rc.local
#!/bin/sh

# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
