This is a really silly request. Please feel free to completely ignore it, especially if it's not easy to implement.

Sometimes I'd like to have the player boot into forced-DC mode, but only once. For instance, to quick-test a piece of software like GPSapp that I only run in DC mode. Or maybe to change one of the DC-specific settings while I'm in the warm comort of my office. In other words, I don't want to have to make two trips into the hijack menu just for the one reboot.

Is it possible to have the kernel look and see if one or more buttons is being held down at boot time, and if so, have it force AC or DC for that boot depending on which button is pressed?

Note that this wouldn't change the flash memory setting that governs the next boot, it would just force the mode for that particular boot that's currently in progress. You wouldn't have to waste any flash bits on it.

Does this sound easy?
