You can accomplish that using a custom IOS.
Acquire the Custom IOS Module Toolkit and build a IOS which writes that value you mentioned to the memory and use this IOS for all software (or patch all IOS).
Then you have it: Slot Light always on. As IOS runs even when in Standby (for WiiConnect24 stuff) it's going to be on even in standby.
