One of the big things will be device support as the new kernel brings
better support. Along with very much improved (or so I'm told)
suspend/resume support.

While this shipping an "out-of-sync" kernel looks like the best option,
it also have it's major drawbacks. So while you might have an -rt
kernel, you might have bad performance from the devices you need the
kernel for.

Make no mistake. This is a major issue that *could* make us skip a
release. In the end, it might be the way to go rather than ship a
release we're not proud of.
