(Newer kernels had a patch that fortunately clarifies that it's a matter of missing _DSD properties)

Your laptop is missing the _DSD entries to setup this device. I suggest opening a support ticket. Hopefully with enough pressure, they'll add the entries. Especially since it doesn't require Lenovo to touch Linux or anything else other than to update their own BIOS images for the affected models.
