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.
