Absolutely, I'll be happy to take rtl8818eu independently from the
discussion on /dev management and firmware loading.

Correct. So far I believe Peter's position was that people still using
kernel older than 2.6.32 should simply use static, but maybe that was a
too restrictive decision.

I think I prefer idea (1) here. It's closer to what we already have,
and as you say, it's probably clearer for the user / easier to document.

Our manual has a complete section about /dev management at
http://buildroot.org/downloads/manual/manual.html#_dev_management, so
this will have to be updated.

Thanks!
