Did you find anything new ?

If I insert the r8169 module then enable runtime PM control on an unused
r8169 device (no cable, never brought up), rtl8169_runtime_suspend is 
called. Same thing when runtime PM control is enabled before the module
is inserted.

I would not mind http://patchwork.ozlabs.org/patch/133590/ going
'Not Applicable' :o)
