Chineese tablets and phones manufacturers violating Linux kernel license

Hello.

Is there anything we can do about the fact, that virtually every Chinese
manufacturer building devices running Android (Tablets and Phones)
violates Linux kernel GPL?

Synrgic, Eanovo, Sidonia, Highton, Lianxintai, Ruyi and on, and on...

Even American companies, like Dell, linger with releasing the source to
they  devices. But Chinese ones just plainly ignore the GPL terms.

This is very frustrating.
One approach is discussed at: http://www.elpauer.org/?p=1146
Is there anything we could do?
