You may need to put the modprobe in your rc.local so it executes at
boot up. I have a bt878 card and I found that I had to modprobe the
lirc driver which then involed the bt878 driver. Try that and see what
happens. For me it was this line in rc.local, but your lirc driver may
be different:
             /sbin/modprobe lirc_gpio

I've seen something about this - search the mythtv archive at

Are you sure you have the correct lircd.conf file? You can download
one for your remote or you can create your own by shutting down lircd
and running irrecord.conf which outputs the lircd.conf settings to the
file you specify on the command line. Are you sure lircd is running?

Again, try the mailing list archive and see what that turns up.
