USB voltage is very tightly-filtered; from the wall, it goes through the computer's power supply and then again through the motherboard's power conditioner. If there were any 5V source that were safe to use with this driver, it would be USB.
However, I'd still wire a capacitor in-parallel with the driver just for that extra measure of safety, and to absorb even the tiniest surge when the device is first plugged in.
Alternately, though I realize it isn't as much fun, Dell sells laptops with backlit keyboards now. I've equipped a few of my coworkers with said laptops, and they've found them to be indispensable when working at night and/or on airplanes.
