pci-id 14e4:4320 reporting rev 02; works only with b43legacy

I built OpenWrt for the Linksys wrt54g v1.0 router, which reports to have a
bcm4306 rev 02 device even though its pci-id is 14e4:4320. This contradicts
http://wireless.kernel.org/en/users/Drivers/b43#Known_PCI_devices , which
says this device should be at rev 03. Not surprisingly, b43legacy works but
b43 does not.
