Well, I can only guess, but you may have a misbehaving application. I experienced something similar on a laptop, and didn't even know it until I unplugged and took an airplane ride. In 2 hours, my 6+ hour battery was dead...an HP scanner driver was consuming 99% CPU even though the scanner was not even plugged into the laptop! Bad me for trusting, and bad HP for a dumb design (or even dumber bug!) If you can, try selectively killing applications until the condition goes away. Also, you didn't mention how much memory you're system has, you may be overwhelming it. And by 'swapper' I presume you mean kswapd? Alternatively, start out with as minimal a system as possible, ie just start a shell, then mount /proc and see what's going on using ps/top, etc. Then manually walk through your system init until you find the offender, if it's userspace at all. Given that you changed kernel versions and still have the issue, that points more towards apps.
