setting primary in multihead xorg.conf causes disregard of DisplaySize

[Felix Miata]

Sent too soon, and probably to the wrong place. I tried equivlent xorg.conf
files with Nvidia G84 and nouveau, and with ATI Cedar and radeon. Neither
have any such shortcoming, so I have to suspect this should have gone to
intel-gfx as a driver bug. Anyone here agree, or know a config solution?
