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.
PSP can be overclocked to 333Mhz too, and I believe many are doing that since it's available and playing non-stop for hours and over Wi-Fi too.

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

@ronaldo in the configuration menü > productinfo
put after the kernel patch this info meens version:<unknow>

I thought it was clear from the beginning that people worrying about device lifetime should just steer clear of overclocking - and the rest have accepted the possibility of a catastrophic failure (assuming they even read the warnings). Oh well, at least there are now a couple of warnings more.

then i updated with App manager (sorry not PC Suite)
and the info in about is not unknown

- Nokia N900 overclocked to 1GHz in bid to outrun obsolescence (video)

since when do we need to overclock our '900s to save them from obsolescence?

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.

All times are GMT. The time now is 05:08.
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).
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.
