We could probably emulate a fake NuBus card in qemu that is just memory in the super slot space for that card. Can a regular driver add RAM, or would we have to detect that in the core code somewhere?
I think a regular driver can do that, if CONFIG_MEMORY_HOTPLUG=y. However, the latter depends on CONFIG_SPARSEMEM. The early core code can just call memblock_add(), though.
