One small sidenote:
If you did _not_ play around with the b44/ssb kconfig options at all,
it would have selected the right options _automatically_ for you.
That means:

cp ../old_kernel_without_ssb/.config .
make oldconfig
make
be done.

You intentionaly disabled PCI device support for b44 and you
still wonder why it doesn't work on your PCI device?
I'm not sure how to make the helptext any clearer on the b44-PCI
option. We have _lots_ of other drivers in the tree that work
EXACTLY the same way, regarding to kconfig. There are _lots_
of drivers where there are seperate options for a "bus-glue".
b44-ssb is no different. And additionally it automatically
selects the right options for 99.9% of the users (you included).

So I'm not sure why you keep bashing the kconfig implementation
here. It's common practice to have seperate config options for
bus-glues and it _automatically_ selects the right options for
you.
