I believe it was solved. The conclusion appears to be that we go with 
how we defined it in this series. drm/$pciid/$regionname. With the only 
regions defined now being VRAM. Main memory will be a followup, but 
requires some discussions on hwo to be prevent double accounting, and 
what to do with the limited amount of mappable memory.
