My /etc/modprobe.conf has the following in it pertaining to LIRC. Note:
I have the homebrew receiver on ttyS1 (COM2).

alias char-major-61 lirc_serial
options lirc_serial type=0 irq=3 io=0x2f8 debug=1
install lirc_serial /bin/setserial /dev/ttyS1 uart none; /sbin/modprobe
--ignore-install lirc_serial

The "install" line is 1 long line. After making changes
to /etc/modprobe.conf run 'depmod -ae'

Make sure LIRC starts apon boot with:

chkconfig --level 345 lircd on
service lircd restart

On my system the module is automatically loaded when lircd starts and
the "install" line in /etc/modprobe.conf takes care of everything for
