setting primary in multihead xorg.conf causes disregard of DisplaySize

setting primary in multihead xorg.conf causes disregard of DisplaySize

[Felix Miata]

Possibly some fault overlap with
https://bugs.freedesktop.org/show_bug.cgi?id=90842 but this is not the same.
I found no other filed bugs similar.

Both DisplaySize and primary display assigned as I wish with radeon.

Both DisplaySize and primary display assigned as I wish with nouveau.

With Intel I must choose between having the DPI I want, or having the primary
display assigned as I wish. Unlike nouveau and radeon, intel won't let me
have both, at least, not using a comparable xorg.conf. I tried on two
different Intel gfx machines (both 4 series, one with pair of 1920x1080,
other with 1680x1050 and 1920x1080), with same failing result.

I ask here before filing a bug to see it there is a workaround or some
specific setup requirement that intel requires and neither radeon nor nouveau do.
