Hm, broken in what way? My expectation would be that it just reports all
connectors as disconnected. That might be irritating to some users, but oth=
er
than that I don't see a real downside. If the HDA controller is runtime
suspended to D3cold, power consumption is identical to the status quo ante.

But yes, just matching for PCI_CLASS_DISPLAY_VGA << 8 instead of
PCI_BASE_CLASS_DISPLAY << 16 would also work, assuming that vendors a=
lways got
this right and never used PCI_CLASS_DISPLAY_3D for a GPU with connectors.
