For reasons we have explicit xorg.conf files for a number of the qemu machines, but not all of them. These mainly disabled screen blanking (which is now down with a separate fragment) but also explictly set the device driver to fbdev which meant they didn't use the modesettings driver as they should (with the virtio framebuffer from qemu). This is the root cause of why the xserver 21.1.16 upgrade doesn't work on a number of machines: the /sys probing changed and the fbdev driver now refuses to use the PCI framebuffer device as there are better drivers, but we've explictly told xorg to use the wrong driver.
