Isn't version 5.2 the latest open firmware for these broadcom devices?
Why are you using version 4.6?

You could also build your own OpenWrt image and select the open firmware
in menuconfig. Then you do not have to do it yourself. I do not know if
this option is available in backfire, but it should work in trunk.

You also need the initivals (b0g0bsinitvals5.fw and b0g0initvals5.fw) in
addition to the firmware itself (ucode5.fw).

OpenWrt takes b43 from compat-wireless, so OpenWrt 10.03.1 contains b43
from round about a year ago and not from kernel version 2.6.32.27. This
version searches in b43-open for the open source firmware and not in b43.
