I've never seen this at least with IBM's firmware.  For example, if I
put in a video capture card where there is clearly no driver the BARs
still get assigned properly.

However, it could be possible that this only occurs if a driver *does*
exist.  Maybe the firmware goes down a non-driver path otherwise.

Are you trying to use the bar reallocation code for hot plug?
