OVMF was never ported to anything but PIIX.
Looks like this is the case. Now I can see that
OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c has hardcoded pci paths in it
corresponding to the pc machine type with PIIX and it tries to access
these devices unconditionally even if they do not exist (as on q35
machine). So this obviously won't work. I think I give up at this point
because I don't know enough about Q35 and I don't see how could it be
hacked into Ovmf. Additionally it seems that this alone would not be
enough to use Apple's boot.efi verbatim but something more complex, very
much resembling Clover would be needed to boot OS X with Ovmf EFI which is
not much cleaner solution than using Chameleon with Seabios that already
works now.
