This should probably go to linux-pci too.

I wonder if this is stable enough to go into 2.6.27?  Most of the PCI bugs we 
have at the moment are related to PCI resource allocation failures.  My hope 
is that finding more space will fix most of them.  Assuming this patch 
doesn't have any dependencies, I can put it in my linux-next branch.

Also, TJ was working on something similar; any comments TJ?

Thanks,
Jesse
