The patch can be dropped, as the latest BIOS release fixes the
problem; lowest and nominal freq are present in the ACPI _CPC package,
and amd-pstate loads without issues.

Here a summary for posterity, hardware and working firmware:

  Motherboard: MSI TRX40 PRO WIFI
  CPU: AMD Ryzen Threadripper 3960X
  BIOS Vendor: American Megatrends International
  BIOS Version: 2.94
  BIOS Release Date: 06/15/2026


Thanks,
