The right track lighting system with multi directional heads could be a cool solution.

… Mark's solution good as well :)

If you are strapped and without power, there are puck lights that are white and battery powered. While these take a lot of juice, they give a great look. You can get them at Lowes or any other home-improvement store. I hope this helps!

There are also LED strip lights. They're very very thin and set up like a ribbon, although you would have to put the driver for them somewhere (most likely in the cabinet below).

Maybe it won't fit your cabinet style, but personally, rather than have lights shining in my eyes (which downward-only ones will, most likely), I'd put what Ikea calls deco-strips along the fronts of the cabinets, about 1/4" toward the wall from the front of the frames.

agreed... puck lights are a good solution and are modern looking.
