No, it's controlled by Archos' firmware.

Yes, Rockbox is started and it's (admittedly buggy) charging algorithm and
screen takes over. You still can use the Archos software for charging if you
prefer, by holding F1 while plugging the (switched off) box in.

It's not hardware, but I don't recommend the deep discharge option. The
modern NiMH cells don't need that, you add extra cycling to them which is not so
good for their lifespan.

It's up to the software "in charge" (nice double meaning) what it does with
the backlight. It doesn't really matter which one you use for charging.

My charging screen uses the backlight as a charging feedback to the user
(Recorder only). When the light is on, it charges; when it's off, charging is
done. So you see it from far away, if the box is not well accessible under a
table, etc.
