I recently ran into a similar problem as yours on my FC6 box, except I have
a ATI USB remote.  I have been running this system as a Myth frontend for
about a year without any issues with lirc.  Then I did the most recent
kernel upgrade and it broke lirc for some reason.  What I found is that
there were three modules loaded for my remote: lirc_atiusb, lirc_dev, and
ati_remote.  I haven't really had time to fully investigate, but it seems
that the ati_remote module wasn't playing well with the other two.  Now,
these coexisted fine on previous kernels, but for some reason won't work
with the latest one.  I searched around on Google and came up with a hit for
someone who had a similar problem under FC5.  He simply renamed the
ati_remote module and that fixed the problem.  I did the same and everything
seems to be working now.  I think I could have accomplished the same thing
by blacklisting the ati_remote module.

Not 100% the same problem as yours due to the different remotes.  But I was
getting the exact same symptoms; modules loading, lircd starting, and then
crashing with the "no /dev/lirc" message as soon as I fired up Myth
front-end.  Perhaps you have another module loading that is interfering with
lirc.
