Thanks to Shadowjk who perfectly explained why the charging shall be executed in incremental steps going from a single to a dual battery setup, now I am able to run until the out of juice point with VDQ=1.
The problem I am facing now is that some watchdog invokes a reboot when my battery tension is still in the 3300ma range. No way for me to get to the 3248ma point! I tried a cycle during which i closed all active progs (but an xterm with bq2700.sh -5 running) and disabled everything radio-related around 3400ma going to offline mode, then patiently waited looking at the tension. When first 329x ma tension appeared, it had been matter of second before seeing my N900 turning off with message "recharge battery NOW" (or what the message is in English language, mine is Italian).

Any clue on what am I missing?
I assume You've tried disabling bme, via (as root):

Code:
stop bme
...?

With bme disabled, You should be able to even drop into ~2850 mV, where Your phone just "dies" from out of power (warning, possible filesystem corruption - don't try it without proper rootfs/optfs backup, it doesn't help in process of calibrating chip, anyway). If stopping bme doesn't help, I'm out of ideas
