Your /dev/lirc device is not setup correctly. I needs a major number
of 61 as the message states. The output of my /dev/lirc* is:

[mythtv at pvr mythtv]$ ll /dev/lirc*
crwxrwxrwx  1 root   root   61, 0 May 20  2005 /dev/lirc
srwxrwxrwx  1 mythtv mythtv     0 Jan 17 22:51 /dev/lircd
prwxrwxrwx  1 mythtv mythtv     0 Feb  6 00:58 /dev/lircm

You'll need the setserial command to release the serial port as you
know. The lircd startup script can be a bit finicky, so I've run the
LIRC related commands from rc.local:

/bin/setserial /dev/ttyS0 uart none
/sbin/modprobe lirc_serial
sleep 2
/usr/local/sbin/lircd
/usr/local/sbin/lircmd

My modprobe.conf wrt LIRC is:

# LIRC
alias char-major-61 lirc_serial
options lirc_serial irq=4 io=0x3f8

This has always worked for me (both on FC2 and FC4, adjusting modprobe
to match serial port settings) so perhaps it will help you out.

First thing though is to correctly create the /dev/lirc node (you can
use mknod for this, however the LIRC package provides a script that
should do this so I'm not sure why you have ended up with /dev/lirc
created incorrectly.)
