Because we (the operating system) know this better than the BIOS writer.
And because this flag is not reliable;

And because this flag is not reliable; numerous systems where tsc(9) is
broken miss this flag in my ACPI table collection, and vice versa.
This flag is new in ACPI v3.0. If

But the do, unfortunately. Again, I have several examples from the field.

Yes, but when possible, we should always prefer actual, reliable, CPU

the TSC should be entirely safe with the current stock-NetBSD (i.e. no
automatic CPU power management), but
