[libvirt] [RFC] Adding a "none" model for video cards

I'm trying to run vexpress-a9 virtual machines (armv7l architecture) using 

The vexpress-a9 doesn't support vga cards, but libvirt adds a video "cirrus" 
video card when there is a "graphics" element in the domain xml. This prevents 
the domain from booting.

At the moment, the only workaround I found is to add the following to my xml 
file :
  <qemu:arg value='-vga'/>
  <qemu:arg value='none'/>

What do you think about adding a "none" model type for video cards ? I know it 
is a bit strange to declare a video card in order to have none...
I don't know the QEMU driver well, but maybe this could be handled by the 
driver ? i.e. "no VGA card when the machine is vexpress-a9".
