Yup, did a rmmod lirc_serial (but I didn't unload lirc_dev) the first time,
but as you saw in the lines below I did a modprobe -r which did unload both.

It doesn't look like the module parameters are either getting passed to
lirc_serial or that they're not being accepted. I'm not seeing any

I also have a Fedora 11 install running 126.96.36.199-167.fc11.x86_64 which I
