Most of the values are stored in the nvram and not in the CFE. At first
the nvram should be read and if there is no value it should look into
the CFE. Now more values are read out because the b43 and b43legacy
drivers needs them.
Some parts of this patch have been in OpenWRT for a long time and were
made by Michael Buesch.
