Default UBUNTU: (config) Disable the QEMU drm driver

When enabled, this driver will provide modeset support for the
emulated cirrus card in KVM (and only KVM, not Xen).
However this currently leads to boot races as grub will cause
generic parts of the efifb driver to get active which the cirrus
DRM driver then has to replace.
By now the cirrus X driver (or unity) has been fixed not to crash
on starting unity. So by disabling the driver we avoid the race and
get the same experience with KVM and Xen.
