Is there no event that you can use to determine when user-space is
available? In the original udev discussion it was suggested to use
IFF_UP, but I did not find anyone saying what the equivalent mac80211
callback should be.

Also this issue can occur when the firmware is only available on the
real root, but the ramdisk contains the b43 module.
