So is shutting off the display sufficient? Is that what the original player does? I would think (from the comments I read about the PIC power controller) that this is not true. Afterall, what is the point of having a PIC power controller that can turn you on ever 15 minutes, if you can't turn your self off?

Also, power is not lost (at least not in my car). Instead there -is- an accessory line that tells the unit to turn off. But the power will remain even if you choose not to. Honest.

What I need is code/docs/etc. that let me power the unit down (or I should say, the 1ma state described in arch/arm/special/empeg_power.c).

I'm not very familiar or good at munging with the linux kernel.
