Would a patch be entertained which uses LocateHandleBuffer for these two but leaves the PCI ROM retrieval unchanged?

Thanks for the clarification, however I don't quite follow: Is the rejection of the patch based on the intent to maintain support for EFI v1.0+ (which isn't an argument for UGA + GOP as lined out above) or is it based on a gut feeling that the patch might cause breakage for whatever reason. (Perhaps firmware bugs? Not sure what is meant here.)
