The only reliable method on my A5 is to jump-start the phone with another 
LiIon battery. Connect up the spare battery and boot, connect the external 
power then swap the battery for the dead one. After a few seconds the charging 
indicator should show flat but charging, and apm or the sysfs entries should 
show more detailed charging status. A spare openmoko or nokia battery is 
easiest, but i've used the one from my mp3 player and a couple of trailing 
leads when both my openmoko batteries were dead. just be very careful with the 
trailing leads!
