kernel: Removing modules do not turn off devices

Hi!

I am testing kubuntu gutsy (next 7.10).
I noticed that removing usb wireless modules, for example, does not turn
off the devices.
This is important for laptops. Devices, when not in use, should be
turned off.
I think this is caused by kernel not being built with devices->USB
support->USB selective suspend/resume and wakeup (USB_SUSPEND) enabled.
Not sure however.

Regards.
