I just did some RE work on some SPROM routines from the Broadcom driver and
found the following:

1. They do a quick check to see if an SPROM exists. Starting at the ssb address
+ 4 * 1024, a total of 12 words (16 bit) are read. If any of them are not 0 and
not 0xFFFF, then a flag for the presence of an SPROM is set. These reads are
done using a routine named bcmjtag_read(). I have not found it yet.

2. If the flag above is not set, then they read the SPROM data from a file that
named /etc/wlan/bcmXXXX.bin, where XXXX is the chipid.

Does the CD have such files?
