It looks It is not kpowersave that specifically brought the problem to you,
but the method it uses to hibernate or suspend. I don't have enough knowledge
in this field yet, but I think it uses some dbus method to hibernate and
there you may find the problem.
I like very much the hibernate scripts to hibernate or suspend, but I don't
know how kpowersave and hibernate can be put together.
My advice is to take a look if you can force unloading the madwifi modules,
also you can try to manually unconfigure the interface, unload the module and
the load the module and configure it back again.
Good luck. Regards,
