I've got this patch series from Dwayne Litzenberger, as a fix for AMD GPU passthrough. I don't have this hardware myself, so I can't test this, but he claims it works. I'm not sure if allowing guest to enable/disable expansion ROM is safe thing to do, but the comment in rom_write for me suggests it is but wasn't considered necessary. Other than this uncertainty, the patches looks good for me.
