It should be. The patch listed should be good as far as I'm concerned 
but needs to be pushed by Bjorn as PnP mainatainer. Generally speaking 0 
wouldn't be a _very_ necesarily invalid value it seems so it's maybe not 
very nice.

If someone wants a changelog though, this should do:

===
PNP: avoid checking unitialized BARs for conflicts

Avoid checking a PCI BAR for conflicts if the BIOS left it unitialized.

===

(Frans: Tested-by?)
