am not an expert on these kind of things.. but I had the same problem 
after a recent apt-get dist-upgrade

until i figure it out i just added a "/sbin/modprobe lirc_gpio" to the 
end of /etc/rc.local

I *do* have "alias char-major-61 lirc_gpio" in my /etc/modprobe.conf and 
I was under the impression this should load lirc_gpio on boot.. and it 
*was* working until this update..

this seems to have fixed things for now..
