Here's the relevant sections from my modules.conf, which works peachy 
for me (and many others), no modprobes anywhere:

# lirc
alias char-major-61 lirc_i2c
# ivtv
alias char-major-81 videodev
alias char-major-81-0 ivtv
alias char-major-81-1 ivtv
options ivtv mpg_buffers=90
options tuner type=2
options msp3400 once=1 simple=1
add below ivtv msp3400 saa7115 tuner
add above ivtv lirc_dev lirc_i2c

My lircd init script is the third one that runs after the mythbackend 
init (S86 and S90). No clue why your setup wasn't working though... :-\
