if it could be totally automated, hands off type of testing application, I would be happy to leave my N900 for a few hours on the the charger at night to let it go through all combinations. I'm currently using a modified Ideal profile with just a higher max frequency and I think I could go lower in voltages on quite a few frequencies. I tried it a few times manually but I gave up, too much hassle.

So yes, I would be trying it ! Just make sure there is a easy escape route, in case the script gets evil and keeps on running...
