Wow really down on modding here aren't we.

As a suggestion, why not invest some money in an Onyx N[fill in number here] for one of their front-lit devices.
Take a day trip over to the Onyx Forum, located here, for additional information:

I don't think the solution to not being able to use a 400 dollar device how I want is to buy an 800 dollar device. I already have a Voyage for my normal books, I want to be able to read the comics and manga that are on my DX. Simple as that. Plus 800 bucks is more than half of my monthly pay, so no way. If I buy any new readers it's going to be an Oasis.

Even getting electrical connections to the LEDs is going to be hard - LED driver electronics has to cope with the way the LED resistance changes as the LED warms up - just connecting to the +ve voltage available in a kindle is unlikely to lead to a happy result. Let alone give you an adjustable light.
Seriously - save up for a new eReader with a front light. Don't waste your money on this project which has no chance of success. UNLESS you're doing it for the fun of tinkering, not to get a working lit ereader.

I'm not looking for something adjustable, just on. From what I can tell I should be able to embed the LEDs inside the front panel all around the screen. With the proper resistors I should be able to tune the light just how I want. The only real issue is where to draw the power from. I don't want to pull directly from the battery as that would require building some kind of PCB to regulate the power draw. These are 1mmx5umx2um SMD LEDs. As long as I can find a 3v source I should be able to wire the LEDs around the screen in series, slap a switch in front, and I'd be good to go. Heck I could even slap in a micro-ceramic trim pot to be able to adjust brightness.
And yeah, this is basically for the fun of it. Since it really hasn't been used in over a year I want to make this thing usable the way I want it. As I said, my big issue here is finding a power rail to draw from.
