Agreed. We -don't- want to remove CONFIG_ISA or other dependencies.
The idea for drivers/net/Config.in at least is that all architectures
can source the file, and be presented with a proper list of devices for
that platform.

For an embedded board that supports cs89x0, as you suggest, defining
CONFIG_ISA is a much better option. Or, making cs89x0 dependent on
CONFIG_EMBEDDED_PLATFORM -and- CONFIG_ISA.
