Thinking more about it I'm more interested in the docs... 
What does that efuse do ? One would imagine that while it isn't fused you 
can install either software or keys to validate software that you choose ? 
Then you could install some noop DRM and fuse the e-fuse ? Just to make 
sure nobody takes control and install their nasty DRM and then fuses ? 
Something similar to the Ubuntu boot loader that boots unverified kernels ?
