1.- Distribute a kernel with some DRM built-in under the GPL.

2.- Claim that such kernel is an effective technological measure to
    protect copyright. 

3.- You are no longer free to modify that kernel, (removing the DRM
    module) or you can be sued under the DMCA, for circumventing an
    effective technological measure. It doesn't matter in what
    hardware are you going to run such kernel. The DMCA implicitly
    imposes an additional restriction to the GPL, but as the
    restriction is not imposed directly by the copyright owner, but by
    the law, it's OK as far the GPL is concerned.
