Disable "acceleration" under qemu
Disable "acceleration" under qemu, since taking the hypercall trap
is really quite expensive and you're better off doing noaccel. Patch
is based on the one by "Adam Jackson" <ajax@redhat.com>
http://pkgs.fedoraproject.org/cgit/rpms/xorg-x11-drv-cirrus.git/tree/cirrus-1.2.0-qemu.patch?id=daccd1c8174623500eddfa297d8ea76a86d3c5d9
