Attached patch moves the registering from e1000_up to e1000_open and
the unregistering from e1000_down to e1000_close. 
It is only compile-tested as I don't have the hardware.

My laptop has the hardware, so I tested it - system does indeed boot
without whinging about this issue.  Feel free to stick in a:

Thanks for the fast fix. :)

I'm going to add the patch to the suspend-2.6 tree.  Any objections?

Subject: [PATCH] e1000e: register pm_qos request on hardware activation

The pm_qos_add_request call has to register the pm_qos request with the pm_qos
susbsystem before first use of the pm_qos request via
pm_qos_update_request.

As pm_qos changed to use plists there is no benefit in registering and
unregistering the pm_qos request on ifup/ifdown and thus we move the
registering into e1000_open and the unregistering in e1000_close.
