The router made with Broadcom 47xx card usually run a 2.4 kenrel with a Proprietary kernel module and a proprietary firmware for the wifi driver by default. But:
- the 2.6 kernel has support for the bcm47xx in 2 drivers:
- b43
- b43-legacy for older cards.
- there is a free firmware called openfwwf for some broadcom cards
- openwrt build system supports both(the free firmware and the free driver)
So all what we have to do is to:
- build a rootfs with support for both
- customize our rootfs to make it act like a router(the init scripts etc...)
