Comment 3 for bug 125384

It's still not buildable here.
I followed your instructions here: https://help.ubuntu.com/community/Install_Lirc_Feisty
but with no results:
# modprobe lirc_gpio
FATAL: Error inserting lirc_gpio (/lib/modules/2.6.22-8-generic/misc/lirc_gpio.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Also compiling from source don't work. Maybe lirc has to be updated upstream.
