My rough plan was to just mmap the BARs and do it from userspace...

Interestingly, I can't reproduce the problem at the moment. On the other 
hand, I'm also far closer to the AP, so broadcast power may have been 
lower? I'm not actually entirely sure what could lead to sufficient 
interference to screw with the DisplayPort link (it seems like it 
happens with both GPUs on the machine, so it seems more likely that it's 
interfering with the signal than somehow screwing with a clock) so don't 
have many good ideas to start with.
