I'm still trying to reproduce the part where it actually runs the
battery down while plugged in, so I haven't applied the kernel patch.
(Perhaps it was accidentally unplugged or something...)  In the meantime:

What's the desired policy for charging?  Could the charger be shutting
off once the battery is full?  I've heard that doing this is standard
procedure for Li-Ions, since they don't like to be continuously topped

My phone is plugged into the charger right now, and says it's not
charging.  It said it was charging an hour ago, so now its just a
matter of waiting...   I'll disable power management, enable wifi, gps,
etc, and see if that gets it to drain the battery while charging.

charger_type contains:

charger 1A mode 1A

enabled usb_present

chgcur is empty

** Update **

I was having some problems with my mail client, so this has been sitting 
in my outbox.  Anyway, I left the phone on the charger last night, woke 
up and it was on with the red and exclamation point in the battery 
status icon.  I pulled the charger plug out of the phone and reinserted 
it, which shut down the phone.  I can't turn it back on, so I'm going to 
buy a second battery and/or external charger today...  It seems the best 
way to reproduce the issue is with a batter that's not nearly full.
