Not that I'm aware of. But I understand why you're asking this - the
hover* style properties. I've never use these properties myself, and I
don't know if they're actually usable. Someone may want to jump in...

Have you tried using two select feature controls on the same layer,
one with hover:true, the other with hover:false? Again, I've never
tried this myself, and I'm not actually sure it'll work. If that
doesn't work, I'd say it's a bug in OpenLayers, and we'll need to fix
it.

Yeah, the selectStyle property of the select feature control matters
here. Again, I don't know whether these hover* properties are usable
(I dont think they are, but I may be wrong).

Hope this helps,
