Today I do a measurable about it.
First I using 2.6.12 without dynamic enable and unplug the AC power,
I check the /proc/pmu/battery_0, like this.
--
flags : 00000011
charge : 907
max_charge : 2863
current : -987
voltage : 10950
time rem. : 3600

I only intresting with current, that show the system power load.
When I enable dynamic, The current can low at -900.
So, It works. :>
2.6.12 + suspend2 + ck3 + dynamic
