It might be but we don't get that far. In their case it could be a problem where the Radeon card is not enabled via ACPI so there are no connectors that show, with our laptop the card is enabled as soon as the PMD is plugged in but the drm/radeon driver cannot read the vbios.
I suspect that the problem with our laptops could be coming from the PCI code since the Radeon card is shown at PCI bus 16:00 but the proprietary ATI drivers only find a card at 22:00 which is never listed in lspci so there could be an issue where the card is not assigned the correct pci bus for some reason and thus the driver cannot read the vbios contents. I created the other bug but I've gotten the standard muxless response and no traction so please post a response here so that maybe we would get some more attention https://bugs.freedesktop.org/show_bug.cgi?id=41265
