I got it working. My kernel, which I build up from defconfig, was
missing CONFIG_HOTPLUG_PCI_PCIE. It makes sense, but I wish there was
more evidence that pointed me to this option. At least we can close the
loop here in case anyone else runs into this problem. As a side benefit,
enabling this option also got the dGPU to enter D3cold where before the
lowest it would get is D3hot.

Thanks again,
