Actually, you can't just force the vendor to open up all of their source code. 
The GPL isn't a contract - it's a license. If a vendor makes a derived work 
from the Linux kernel and does not GPL-license said derived work, they are 
indeed violating copyright as the license the GPL provides no longer supports 
their ability to redistribute.

However, the court decides what happens to the vendor. The court might force 
the vendor to open up their code, but to my knowledge this would be breaking 
brand new ground. I think it is more likely that the plaintiff could be 
awarded monetary damages and the defendant enjoined from further 
redistribution.

The charge is not "violating the GPL" (since the GPL is not a contract) -- 
it's distributing copyrighted materials without a license. See Eben Moglen's 
discussion on this subject for more details.
