When your N900 is idling, fire up top (preferably via ssh session) and see
whether pulseaudio is constantly eating 2-5% of CPU. If so, run "killall
tongend" as root. This is a bug fixed in PR1.2 (afaik) which seems to be
launched sometime between today and the next decade.

Also, BatteryGraph application from extras(-testing?) helps "debugging"
battery usage a lot. From what I found, the *greatest* *ever* battery hog is
browsing web via 3G. I do that daily while commuting to/from work and it can
take up to 40-50% of battery within less than an hour!
