I suspect that systems where ACPI indicates that the clock speed
may change as a result of power management events should set this
automatically so people don't have to hack up their system with
sysctl's just to get things to work, when it's well known that
the system selecting TSC by default on systems with a variable
processor speed will experience problems otherwise.

I'm guessing what changes in the patches is that the default for
preferred clock changed to the wrong thing.
