For anything using kernel 3.14+ IMO the answer to pretty much *any* gfx
issue is "use stdvga instead of cirrus".  3.14 got a kms driver for the
qemu stdvga (bochsdrm), so the modesetting driver and all the modern
stuff such as root-less X server works with the stdvga too.  And the
constrains cirrus has (due to emulating existing, old hardware) are
gone.
