Sorry about taking a while to get back to you.

Previously I needed the busn work to get it working, this was included
in the resource-alloc branch. It never worked on mainline, the bridge
used to show up but never get scanned. Now it's not showing up at all
on hotplug. It could be a dock driver regression.

No, the only unusual option is I use pci=nocrs since the bios is
completely ignorant of support for 64bit BARs.
