Something worse than "these guys"! ;)

With the XO-1 being EOL some time now and the ones in the field aging some "dangerous playing" might not be unthinkable.
As you know kids are notorious for not "playing safe"...

The thing is that XO-1.5 has about twice the XO-1 processing power and is quite usable. So getting another 50%+ out of the XO-1 (albeit with risks) may keep it in stride with the new software versions a bit longer. 
Of course I do realize that this should have nothing to do with OLPC, thus the vague questions ;)

But may be all this is irrelevant now as pushing  the XO-1 to 600MHz (extrapolating from "these guys") results in kernel panics and/or errors.

If this is because of the protection mechanisms I would appreciate if someone lets me know off-list (I promise not to tell) of a possible way around it.

Thanks
