Nice :-)

Did you do the make install part?

lirc_dev doesn't have these parameters. Don't use them.

Where did you see these parameters applied to the lirc_dev module?
Some modprobe.d file in /etc?

Yep.

This means that lirc_wpc8769l couldn't find those symbols, that should
be provided by the lirc_dev module.

You don't need to load lirc_dev manually. Simply modprobing
lirc_wpc8769l should bring in lirc_dev automatically as a dependency.
If it doesn't work, there are only two possible reasons for it:

 1. lirc_dev couldn't be loaded. Try modprobing it and checking that
it's loaded by using lsmod. Check for errors by looking at the end of
the dmesg output.

 2. Somehow your system found a lirc_dev.ko file from an old (not the
CVS version) lirc version, a version that provides
lirc_(un)register_plugin instead of lirc_(un)register_driver.

If it's the second case, do this:

find /lib/modules/`uname -r` -name lirc_dev.ko

and be sure to delete any instance of lirc_dev.ko found. Then do the
"make install" for lirc again, and check that it has installed both
the required modules:

find /lib/modules/`uname -r` -name lirc_dev.ko
find /lib/modules/`uname -r` -name lirc_wpc8769l.ko

Once this is done, ensure that both modules have been unloaded:

rmmod lirc_dev
rmmod lirc_wpc8769l
lsmod | grep lirc

And then try simply loading the lirc_wpc8769l.

modprobe lirc_wpc8769l

It should load with no parameters.

That's it. You still have the old versions installed.
