If you don't flash your box, you have no chance to get it running by simply
switching on power. The original Archos firmware will always hang at the
charging screen and there's no possiblity for Rockbox to change that because
it hasn't been loaded yet.
You'll either have to flash your box and change the Rockbox code or you'll
be stuck with the HW solution.

Your jukebox will power on as soon as it gets power from the DC IN jack.
Then the Archos firmware starts and tries to detect, whether there is power
connected or not, in order to decide if it has to go to the charging screen
or to the directory browser. You have to remove the power again between
these two events.
It's easily done by hand (just to understand how it works): switch your
jukebox off, then insert the power plug, as soon as the green light goes on
remove the power plug again. That's it.
If you want to do it automatically, you'll have to find the appropriate
IIRC, there were some schematics of a very simple circuit somewhere here in
the mailing list or in the archosjukebox6000 yahoo group.
