Ok. I dived into b43 and it does disable the wireless core in the
.stop() callback. So I believe it does reinitialize the device when
.start() callback is being called after resume. So I think you should
check the chipctl register at the end of the .start() callback.

I assume you mean bcma instead of b43, right? I admit it is a bit shady,
because bcma is more than just a bus driver. It also contains drivers
for the chipcommon and pcie cores on the device.
