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.
