That might also explain why Dirk doesn't see it on his other machine. The other machine doesn't have a buggy ACPI table bus limit. So yeah, trusting actual hw more than the _OSC entry sounds like the fix. I don't understand why hardware designers seem to think that ACPI is a good model, when it would have been so much better to just introduce hardware standards instead. Oh well. I guess that boat sailed long long ago.
