Actually its fixed for me in the netbsd_7 build I did on 21/11/2015 with 
sources checked out from that day.

I still see the:
DRM error in intel_uncore_check_errors: Unclaimed register before interrupt

message but i get one of them when the screen blanks and then the system 
goes properly idle with no interrupt storm so I assume someone added the 
code to disable the interrupt in that scenario until the screen is 
unblanked.

Will probably be putting a more up to date kernel on there sometime in 
the next week or so I'll test again then.
