Due to hardware limitations, anything past 400MHz is impossible.

The OMAP2420's specs do no such thing. OMAP2 can go faster, but the OMAP2420 does not just like Core 2 Duo can go into the 3.0GHz range, but many models of the line do not.
The issue is also compounded by the mobile SoC nature of the OMAPs compared to a typical computer setup. Overclocking a desktop computer's CPU doesn't have the system-wide effects that overclocking a mobile SoC will have (like, say, burning out the wifi radio).

Then am i right in saying that the hardware of the Nokia tablets has an absolutely different structure compared to the a pocket PC or a palm?

But you should not compare devices like tablet vs pocket pc, you should refer to the core chips instead.
Of course the system clock oscillator affects clocking generation, but constraints are coming mostly from the dividers available for obtaining a certain frequency for a certain HW block in the SoC.

On a side note, I just wanted to say "Thanks!", Igor, for dropping in and spreading a little of the wisdom around. 
It's always appreciated when somebody with the knowledge takes the time to explain and clarify things for those without—especially things related to the mysterious world of OMAP.

Hi all. I am also curiousc about the overclocking capabiilities of Nokia N810 TI Omap 2420 cpu. Unfortunately , TI site is woefully lacking in information , apart from the ”up to 1 Ghz” assertion.
whilst I do understand that such an endeavour entails some risks , I am at a loss to understand why so little information is out there about this issue.
Therefore I would ask tthe people that have the knowledge about clock/multiplier dependencies for the TI Omap 2420's CPU and components to post a more ellaborate answer.
Since a leap from 330Mhz to 400 was possible , I think that we are far from tapping out the chip's performance.
A hardware spec sheet for the chip would be great.
Cheers

Incredible as it may seem , yes , I did read the *entire* thread .
And, have been scouring the net for more information on this issue.
As I've said, there's very little information of any use regarding this.
If you have no useful additions Antiles, it might be more useful to refrain from posting rather than making snarky, uncalled for comments.
My comment was directed to any Nokia folks possibly browsing this forum (or any other person knowledgeable in Omap internals), to come forward with a bit more information, maybe even the datasheet for the chip that TI is not making available for the general public.
