Attaching a patch against hardy-proposed.

** Description changed:

  (Note: This is a direct copy of my bug KDE bug report at
  https://bugs.kde.org/show_bug.cgi?id=153877)
  
  I have two Logitech Bluetooth Mice: One MX900 and one MX1000 on an HP Laptop with integrated Broadcom Bluetooth connectivity. I can pair both easily using the tray applet, and they both work flawlessly initially.
  However, after some time of inactivity (Not using one mouse for some time, Going away from the System, etc) the connection is lost and won't be re-established, even after moving the mouse constantly.
  
  I go to Configuration -> Input Devices and both Mice are listed. The
  mouse that hasn't been used for some time (don't know the exact amount),
  doesn't show the yellow star in front of its name any more (The other
  one in use still has the yellow star). Selecting the inactive mouse and
  pressing "Connect" doesn't help. I can only re-connect if I press the
  "Discoverable" Button on the mouse and then press "Connect" in the
  dialog.
  
  The effect is the same with both mice. The disconnection happens always
  after mouse some inactivity time. This bug makes Bluettooth mice
  operation under KDE currently not usable at all.
+ 
+ -------
+ Bug Impact: Currently all users of bluetooth input devices will be unable to use their input device after leaving it idle for an extended period of time.  The only workaround is to unplug and plug back in the device again.
+ 
+ Addressing: Upstream has a patch in CVS head  that works around the
+ issue.
+ 
+ Test Case:
+ 1) Install Ubuntu on a system with a supported bluetooth controller.
+ 2) Pair a BT mouse or keyboard with the computer.  Verify that it works
+ 3) Disable any suspend when idle options on the computer
+ 4) Leave the computer idle for 30+ minutes.
+ 5) Verify that the mouse and/or keyboard have stopped working.
