A read of all 1's is a symptom of reading a non-existent register. I would 
certainly suspect the adapter.

I have a PCI Express extender for my HP laptop. Although it avoids the problem 
of the white-listed WLAN modules in the BIOS, not all cards work with it. 
Perhaps there is a critical timing issue.

I just tested again. My BCM4322 (14e4:432b) works with both b43 and wl in the 
extender. For the record, the upload speeds are 8 Mbps with b43 and 15 Mbps with 
wl in the 2.4 GHz band (router max 54 Mbps). In the 5 GHz band, the router is 
set for 270 Mbps max and wl gets 80 Mbps. Of course, the 5 GHz band in b43 is 
inactive.
