No, not yet. I'm having a hard figuring out the new firmware API for
those new devices. Working on it..

Note the tiny difference in here ;)

Intel(R) PRO/Wireless 2200BG
vs.
Intel Centrino Wireless-N 2200 BGN

There are like 10 years in between. :)

Just to clarify, the 0x4222 is for iwn(4), adding the IDs there is the
first step, followed by a new firmware module and some glue code.

I already thought about adding just the firmware but not the IDs yet,
for others to tinker with. Issue is that this would generate
regressions with already working cards, eg. 6230. So, eventually..
just not yet.
