The theory behind the blank was that the kernel would not
re-initilize the display on boot (and leave it to whatever
the bootloader configured it to) until after the first
blank request.
On some devices, the bootloader does not turn the screen on,
but it's done by the kernel and thus. This makes the extra blank at
start unnecessary.

This can be launched from an 'on charger' section in init, which
is processed if androidboot.mode=charger is supplied on kernel
command line.
This is a standalone binary that has a simple "user interface"
and allows the standard production kernel to run while charging.
This removes the burden from the bootloader to get low-power mode
working.
Currently, the device will "power-on" (i.e. reboot) into normal
mode if the power key is pressed for X seconds, and will also
power down the device if the usb/ac cable is removed for Y seconds.
