On some bios there is an option for "legacy cxl" which produces the nvdimm-esque behavior described above. After further investigation, supporting this would require a bigger lift than i expected since the existing emulated CXL devices don't carry any kind of node assignment and we'd have to plumb that through Not worth it, better off working towards the new stuff.
