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
resume for me. I'll submit it to the lirc list and let the maintainers
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.
