Title:
  rt2500pci wireless interface not functional after suspend/resume

Bug description:
  Following an upgrade to Intrepid on a system where the rt2500pci
  wireless was working in Hardy using linux-backports-modules, the
  wireless interface still works on startup but becomes non-functional
  after a suspend/resume cycle. The following error can be seen in
  syslog from NetworkManager:

  NetworkManager: <info>  (wlan0): now managed 
  NetworkManager: <info>  (wlan0): device state change: 1 -> 2 
  NetworkManager: <info>  (wlan0): bringing up device. 
  NetworkManager: <WARN>  nm_device_hw_bring_up(): (wlan0): device not up after timeout! 

  and attempts to bring the interface up manually fail:

  $ sudo ifconfig wlan0 up
  SIOCSIFFLAGS: No such device

  even though the interface does appear in the output of "iwconfig" and
  "ifconfig -a"

  Reloading the module with:

  $ sudo rmmod rt2500pci && sudo modprobe rt2500pci

  seems to get the interface working again.

  
  lspci -v output:
  01:03.0 Network controller: RaLink RT2500 802.11g Cardbus/mini-PCI (rev 01)
  	Subsystem: Micro-Star International Co., Ltd. Device 6833
  	Flags: bus master, slow devsel, latency 64, IRQ 21
  	Memory at ffcfc000 (32-bit, non-prefetchable) [size=8K]
  	Capabilities: [40] Power Management version 2
  	Kernel driver in use: rt2500pci
  	Kernel modules: rt2500pci

  This occurs using both the default rt2x00 modules included with
  Intrepid, and the ones in linux-backports-modules.
