Now that I have caught up with all the latest stuff, I managed to build 
xorg-server-1.17.0.

Man page for modesetting driver shipped with xorg-server-1.17.0 mentions the 
following:

Option "AccelMethod" "string"
       One of "glamor" or "none".  Default: glamor

So, you could try and create the config file and set AccelMethod to "none" when 
in Qemu.
