Hmm, not sure if this is related but I lost close to 40% of my battery power yesterday with the device in my pocket doing nothing in just a few hours. No widgets, email set to manual, no data connections - it was literally sitting there.
After killing wlancond - the battery stabalized. It still dropped faster than I would expect, but nowhere near as bad.

I'll try and stick powertop on later today and see what's happening.

Oops. Just found this post. I guess it's the same thing: http://talk.maemo.org/showthread.php?p=418901
