My apologies -- it's been in my to-do list to send this small patch to
the LIRC maintainers but I keep neglecting to do that. I don't know if
if the patch is correct, but without it LIRC stops working after S3

decide if the patch makes sense, or if the problem needs to be handled
in a different way.

Yes, patching the 0.8.4a driver given that Alan has a 0.8.4a lircd seems
like the easiest thing to do here.
