One final thought on this...run powerd from the command line with the '-v' option so that you can see if it is trying to change the frequency. If it is (and I am pretty sure that it is), you can remove powerd from the list of suspects. If this proves the case and new BIOS and EC code does not fix the problem, you might try acpi@freebsd.org as the there are people there with the expertise to better diagnose ACPI issues than I. -- R.
