It's 5 years only, when the cpu runs at 600Mhz (or 720) _all the time_ when it's running. But as the n900 switches clock - the math to calculate the lifespan goes far beyond basics.
Simple as that: we cannot say for sure how many days/months/years the lifespan will degrade. Absolutely sure seems to be, that there is _some_ sort of degradation *sing* - but I guess no one of us (hardcore-gamers excepted - they should've bought a psp in the first place *g*) will see a dying cpu the next few years.

Are we sure this is related to the kernel flash?
I flashed it to the 900 Mhz and my Settings, About product reads:
Nokia N900
Maemo 5
Version: 3.2010.02-8.203.1

Another interesting thing is that the expected lifespan is longer when running constantly at maximum 600MHz clock frequency, than jumping between different clock frequencies arbitrarily. Maybe it's somewhat similar to lightbulbs lifespan (they also fail faster if you turn them on/off frequently, than just having them permanently lighted).

Oh man this got really out of hand. I bet nobody even reads the warnings about device wearing and other numerous problems that come with them.

But the point is still the same. If most of omap chips can run safely at very high clock frequencies, I guess TI would bin them and sell really lots of high speed chips, blasting the competition (snapdragons, etc.). This does not seem to be happening.
