Does the new ACPI code work with bigsur?

Does the new ACPI code work with bigsur?

[H. J. Lu]

2.4.21 kernel has

ACPI Subsystem revision 20020517

and works fine on bigsur. Has anyone got

ACPI Subsystem revision 20030619

working on bigsur?

what firmware are you running?  this is a common problem with bigsur-era
