boot while charging

[zr2ee]

i'm doing an install on my 06 tacoma using my dell streak 7, since the battery life isn't very good im looking for a way to change the boot loader to boot the device whenever it has external power applied, my original droid would boot with external power and my optimus v does it now with the cyanogen mod rom it has so im sure it's possible. is there any current roms that do this? or any known method of changing this?
