I tested the same and got the same result.
I suppose BigSur doesn't support the button feature in its
firmware.
If it does, you should see "ACPI: Power Button (FF) found" in
boot message and you will see a /proc/acpi/button directory.
If the button event is properly processed, you can see
"button power 00000080 00000000"
line when you cat /proc/acpi/event.
Thanks,

Yes, I see this message upon boot, and the /proc/acpi/button directory
is created.

Nothing seems to get written to the event file.

Hmm...
Can you check /proc/interrupts and see any interrupts on
acpi line?
Oh well, our BigSur says
39: 0 0 IO-SAPIC-edge acpi
But ACPI specification says the SCI (ACPI interrupt) should be
active low, level and shareable. I'll look into it...
Thanks,
