The nmi watchdog changed for 2.6.36, such that it increments every 60 seconds instead of every second. Using cpuspeed and a lightly loaded system, will delay it even longer. This is a good thing as you don't need nmi interrupts firing all the time.
But if after sticking a load on the system for 10 minutes, the NMI interrupt doesn't increment, then I would be concerned.
