I still have the same remark about regulator-boot-on but this isn't a 
blocker per-se.

The Oops I alluded to in my answer to the Jaguar patch is triggered by 
making DRM_ACCEL_ROCKET driver built-in instead of as a module. I'm not 
sure how much I will debug this on my side, I'll prolly just report this 
on the ML in a few hours.

Thanks!
Quentin
