As far as I can tell you're _thinking_ of adding changes to drivers that are not in fact even used, nor will they _ever_ be used since we won't have a Lucid DOM0 host unless we provide one via an LTS backported kernel. In which case the point is moot.

As I read it, this is for Hardy where we do have dom0, and not Lucid because we don't support dom0 there.

My big question when looking at the patch was why combine the two patches its based off?  I found it hard to look at and compare the patch that way.
