It has everything to do with the 'enable' file. The 'enable' file lets you change the state of the hardware without an ownership mechanism. Other device users will not be notified of the state change. Since the other users can't be sure of the state of the hardware when they are activated, they will have to reload their state into the hardware on every activation.
Jon you seem to miss the fact that this can be done now without the enable flag, setpci can be used to disable the BARs, again the enable flag doesn't change that....
