The ACPI tables are missing? But even without those, a strong hypothesis is
that the motherboard and/or BIOS vendor simply forgot to supply the CPU
frequency tables within the firmware image. All CPU PM drivers (est(4),
powernow(4), acpicpu(4), odcm(4)) now "race" for the best match.

If you have time, you could add some of this information to the quirk table
in acpi_cpu.c (should be clear enough; but see pmf_get_platform(9)). Funnily
enough, the vendor(s) also put some copy-paste information to the "system"
fields in the DMI/SMBIOS, so you'd probably use the board or bios -fields.
