Looks like Dealextreme has up an 800mA driver, designed to step down voltage between 3.6V and 9V. Unlike the Kaidomain circuits we were seeing before, which appeared to simply have a few diodes and resistors on a board, this one clearly has capacitors and an inductor, which suggest a buck circuit of some sort.
Interestingly, they're also selling bare reflectors for the Cree LED, so it looks like this driver, and the reflectors are essentially the components to the Ultrafire Cree drop-in module.
