OK, thanks. If you wish you can edit net/wireless/b43/main.c and find:
BCMA_CORE(BCMA_MANUF_BCM, BCMA_CORE_80211, 0x1D, BCMA_ANY_CLASS),

Then add
BCMA_CORE(BCMA_MANUF_BCM, BCMA_CORE_80211, 0x1E, BCMA_ANY_CLASS),
below the line you found.

This will make b43 try support your card but it will fail after
detecting unsupported PHY/RADIO.
