I installed Google Chromium while using Witter and listening to this week's Economist and browsing the net, so Lehto's undervoltage 800 mHz kernel seems to be working well on my N900. Battery usage while doing all that was not zero, no big surprise

I really don't have any battery measurement going on, so I am just relying on guesswork to say that battery usage was not horrible and not wonderful.

My N900 is working so well I hesitate to change it. But I'll probably test the newest Titan kernel...
