I'm trying to use my old N770 (running OS2006) as a screen for a carputer, and want it to turn on when power is applied to the charger port.

I've so far, by hacking linuxrc in initfs, got it to show the main home screen (i.e. with menus and stuff) before the big black Charging screen appears. I haven't managed to get networking going in this state, so I can't ssh in and look at what processes might be causing the Charging screen (which I'd like to replace with my own code).

Any ideas as to how I could bypass this?
