At the moment we do not know the location of the display size fields
in the radeon bios tables so we don't actually know the physical size
of the panel.  The older mergedfb driver had code to attempt to
calculate the dpi based on the attached monitors along with some
fallbacks.  You should be able to specify a monitor for the LVDS
output and set the display size there.  This should work, but I
haven't verified it.

Not sure on this one.  what versions of mesa and the drm are you using?

You might try changing the migration heuristic for exa.  I think
greedy or always may improve things.  Either way, at the moment exa
only really helps when using composite.
