Seigo: Spark answers

Those folks sell a lot into the western markets, where IP licensing compliance issues have to be on the up and up. Zenithink, Ainol, Momo, etc., don't. They sell out of shady Honk Kong distributors to places all over the world to places where a lack of GPL compliance isn't something that would get them shut down.

When Seigo says he has most of the kernel sources + some blobs, he is referring to the sources provided by the chipset manufacturer. However they don't have the source to the modifications Zenithink has done.
