Yes, I'd say results are mixed. B43 now says it wants 20dBm and it's getting
16.75 but iwconfig says rate is only 1Mb/s and I can't keep the link up long
enough to be usefull.
If the SPROM was wrong all along, why does it work fine with bcm43xx?
Incidentally, when I rebooted and while the 4306 was still connected,
NetworkManager said he saw 100%.

More food for thought:
My BCM4306/2 in a Cardbus format has a maxpbg value that translates to 10 dBm.
It routinely transmits at 5-6 Mb/s in my normal setting. When I reprogrammed the
SPROM to 20 dBm, it would start out at the above rate, then rapidly drop to 1
Mb/s. It looked as if the radio was overheating. It is possible that the patch
of today will make things worse, not better.
