Well, no. There is not a magic limit of 4 hours uptime as I suspected yesterday late in the night :-) In fact, the last test I did gave me 6 hours! (Again almost exact, oh well). The difference with the last one was that the wifi card was not connected.
So that's what I did: I installed a crontab like this one in my user account:
* * * * * (/bin/date; /usr/bin/apm) >> /home/fquindos/up.txt
Then, with the yellow led off, I disconected the power supply and closed the lid. This morning the unit was off (surprise). Clicking the power button the green led went on for about a minute, but nothing appeared on the display. Not possible to start the unit without power supply. Examining the up.txt log file I found:

iamasmith, do you test with a network card?
Really strange. Always 4 hours exactly. I'm testing battery life in my 3200 this time with no CF card attached. I'm wondering if the battery is really empty and is not possible to start the unit without powering it. Or if after powering the unit just enough to start it, battery runs for hours (4 again?). This smells to "feature" :-)
