This is on a rather new device 20080626, probably A6 (have no torx atm :-/ )
The effect is 100% reproduceable for both booting on old and not booting on
new U_Boot. Only randomness is AUX-LED flashing very short (<0.1sec) when
fail on normal boot w/o bat, whereas it flashes slow (~0.5s on) for 4
to "4.5" times with a dead Nokia BL-5C. Result no boot on new U_Boot anyway.
