This whole problem just shows that it was a mistake in the first place to try to redo the BIOS work in Linux. If BIOS doesn't supply MCFG Linux trying to create one (or in general having generalized resource allocation) is just a big mess and will cause endless problems. The standard resource code is just not up to the task and it needs very intimate knowledge of the hardware that the kernel shouldn't have.
Again the real fix I think is to just drop all that code in git-x86 again and finally fix LinuxBIOS to do its job properly and pass a proper MCFG (or just forget about using mmconfig with LinuxBIOS - it is not that Type1 suddently doesn't work anymore). Then this code wouldn't be needed at all
