lirc_it87 only recently gained auto-loading support. You apparently
have an it87 device in that box. I'm guessing that previously, that
driver wasn't loading.

lirc_i2c is loading second, so the IR you want to talk to is
/dev/lirc1 instead of the default device. The config you posted later
in this thread is using defaults, which will connect to /dev/lirc0,
not /dev/lirc1. Blacklist lirc_it87 and reboot (so lirc_i2c is the
only ir device driver loaded) or point your config at device
/dev/lirc1 and you should be back in action.
