The option is still valid, but the init process is way less aggressive.
Chip isn't arbitrarily reset/reconfigured anymore, and temperature
limits are preserved. Thus what the option was trying to prevent is
probably not happening anymore in the first place.

That part of the init process was actually removed in 2.6.6. Believe me,
you are not the only one to have complained about that nasty behavior.
