I might ask you to try two things:
1)Install Battery-Graph (NOT Battery-Eye) and let it do its work of measurement.
2)Install HTOP and when showing the processes, click it so that it will sort by TIME (not CPU%).

With this, I would guesstimate:
1)If it is some rogue program consuming battery, batterygraph will show you (not which program, but that the processor is constantly being used).

2)With HTOP in sort by Time form, you should probably capture the culprit by looking of the time consumed by the program (although lots of times they are disguised so, it should be difficult).

3)If HTOP didn't help, and you say you did a total reflash (otherwise I would say to you to run
cd /var/lib/dpkg/info/; ls -lrt *.list; cd ~
which would list EVERYTHING installed/reinstalled/updated by date ):

a)You might have a problem reported related with 3g and e-mail. I Would ask you to measure the phone WHILE OFFLINE, AND without the SIM card.

b)You have a broken phone.

If either a or b be true, you will have to change your n900 for an e7 or n9 (that's the same of sending it to a nokia care).

Of course, that's MY guesstimate. Sorry |:/

I'll give your suggestions a try this evening (gotta get back to werk!)

I'm leaning toward B, broken phone, but it's not broken enough to toss it out. I got it as a refurb, so no warranty. Mostly using it as a development target.

One thing to note, I ran the command to list installed pkgs and got the following:

Nokia-N900:~#
The stuff from Sep. 29 was everything from yesterday after I reflashed. Is the stuff dated Sep 10 2010 normal after a reflash? I only got the phone a couple months ago. Are the 2010 dates just embedded in the firmware updates or should they all show the current date?

Thanks for the help!

Well, I think I'm just gonna accept that I've got a hardware issue with my n900. It works fine otherwise.

To sum up for future reference:

Device drains batteries at 300-400 mA when disconnected from the charger, even with very low CPU usage and powertop reports most time spent in c3 & c4 sleep states. When on the charger, it pulls 0-20mA.

Even if powered off, it warms up & drains the battery in a couple hours.
So I'm guessing there's a short somewhere in the power management/charging circuitry.

Does it draw power also in offline mode?

Yes. It draws power even when turned off.

So, for the last 8 months (since I bought it), my N900 has never lasted more than 3-4 hours and would drain even when powered off. It was basically always plugged in and onlyused for hacking or playing tunes in the car. I became accustomed to it being a nice pocket heater.

The other day when i pocketed it it wasn't warm. I thought it had died. To my surprise, it was still on and had a full battery. Then I left it in the car for ~6 hours and it still had 70% charge left.

WTF, it has healed itself! I'm getting 8+ hours per charge.

Same old batteries, latest CSSU, overclocked, dev & test repos enabled. All hardware enabled. Not exactly optimized for battery life.

I don't get it but I'm glad its staying alive all day.
