I'm not really hot on the logical underpinnings, but I don't remember  
running into any substantial problems when applying SPARQL over RDFS.  
There are some questions around how you handle certain queries that  
theoretically have infinite solutions, but there are pragmatic  
workarounds for those. I'm confident that whatever solution SPARQL/OWL  
proposes here will be applicable to SPARQL/RDFS.

I would imagine so.
