With those changes the "arguments longer than property" message does go
away. I now get this probe error:

Meanwhile I got private repsonse that somebody have a working openlabs
module on a beaglebone, so it's _really_ possible! :-)
Thanks for all the help. My BBB now works with the openlabs radio. I
had P9_28 & P9_30 in the the wrong holes (blush).
I still have those two messages at modprobe time, but the radio is probed.

I'll test e..g ping6 to another BBB and Pi ASAP.
Here is what I appended to the existing am335x-boneblack.dts file:

&spi1 {

pinctrl-0 = <&spi1_pins>;

};
I'll post the J1 to BBB P9 pin mapping ASAP as well.
