After the changes proposed in Bug 827503, S3/S4 will be enabled by
default on qemu/seabios, but we want it disabled by default in RHEL6.4
to avoid problems on problematic OSes (it'll be enabled on a
case-by-case basis in the management layer).

Since we want to have it fully supported when enabled, QE should perform
the expected tests (which AFAIK have been run in rhel6.3 already, so
enabling it manually should not be a problem).
