yeah, i'd support the removal of it too, if the transition is smooth and
the regressions are resolved. And it should be smooth, as long as users
are able to load the firmware blob, right? There's also an entry for it
in Documentation/feature-removal-schedule.txt:

What: bcm43xx wireless network driver
When: 2.6.26
Files: drivers/net/wireless/bcm43xx
Why: This driver's functionality has been replaced by the
mac80211-based b43 and b43legacy drivers.
