My plan is to continue to maintain bcm43xx-SoftMAC for at least the BPHY and 4306 revisions even
after d80211 becomes the in-kernel driver. Of course, I hope that we will have found the killer bugs
by that time, and that maintenance will only require following kernel API changes.

Just to make sure I'm understanding this correctly - does the v4 
firmware drop compatibility for older cards, or is it just that Broadcom 
dropped support in the driver at the same time as the firmware changed, 
and the new firmware will still also drive the old cards?

We can't extract bcm43xx_microcode2.fw from v4 drivers. You need this 
file for old rev2+3 0x812 cores. So we don't know what firmware we 
should load into those old cores. I think broadcom never developed a new 
v4 style firmware for their old hardware.
