Just out of pure curiosity, and this could be WAY off base, but have you
checked that with the new kernel your serial port you have the IR Blaster
connected to isn't being used by another process, like mgetty?

It's been a LONG time since I've setup LIRC (I am anal about copying that
configuration across upgrades and backing up the boxes before
re-installations) but I seem to remember something about having to turn off
the serial port in init or otherwise taking control of it away from the OS
for LIRC to pick it up.

Again, it's been a long time and I may be way off base here.
