The old situation was fine. All the resources were mapped. Sure, there were ROM resources that aren't even enabled, but that is _normal_. Iirc, several graphics chips actually alias the ROM resources with the regular memory-mapped IO resource, ie you can't even map both of them at the same time at some separate address, because the hardware shares address decoding resources. There's a reson PCI ROM resources are treated specially by the kernel. And as far as I can see, all the other resources are already allocated even without your patch. So there is some fundamental _bug_ there. This is not about enabling/disabling your patch, this is about your patch apparently simply being wrong. But maybe I'm missing something.
