I wish we could do better than just a version check; is there anything
we can probe in QMP, or possibly even use qemu 1.5's
query-command-line-parameters as an additional method for checking when
this has been backported to a build earlier than 1.2?  At any rate,
don't let that hold up this patch; we can improve detection methods as
followup patches when (and if) a downstream distro even decides to
backport websocket support.

Not sure this last sentence adds anything here.

Comment needs fixing.

Rest of patch looks fine.  ACK with problems fixed.
