I'm a little confused about the setup. was still thinking about the resets. Do you use the starter? That can make a large voltage drop as well.
you are using an external 8v regulator and an 8 ohm resistor? That might be overkill, dunno.
but just an 8v regulator should not add any noticable milliamp drain.
FYI I am currently using a 470uf cap and two .1uf caps with the regulator, and low power backlight, which is not fed through the regulator (schematic in post 8), but rather is fed 12v through a resistor and has the bottom leg pwm'd. So it is a sort of switching power supply just for the lcd backlight.
