You're predicating this on the assumption that the ability to break broken 
monitors even further has something to do with the unix privilege model.  I 
remain thoroughly unconvinced of this.

And you really are wishing the problem away, unless you can guarantee that the 
registers controlling mode setting never get mapped into userspace, and that 
the DMA you trigger from the DRM never writes to those registers.  Can you 
make that claim?
