There is [1], but it doesn't get updated as frequently.

Oh, right.  The relevant Debian-specific change is 

  * Enable BCMA as module, BCMA_HOST_PCI and B43_BCMA (Closes: #649567)
    but limit these to devices not supported by brcmsmac

To get brcmsmac, disable BCMA:

	make nconfig
	 Device Drivers → Broadcom specific AMBA → BCMA support: N
	 Device Drivers → Network device support → Wireless LAN →
	  Broadcom IEEE802.11n PCIe SoftMAC WLAN driver: M

Or from the command line:

	scripts/config --disable BCMA
	scripts/config --module BRCMSMAC

Sorry for the fuss.

Sincerely,
Jonathan
