Haxr provides a basic implementation of the XML-RPC protocol, and while it looks like it doesn' t build on 6.10 at the moment, getting it to build shouldn't be a problem, and although it doesn't appear to be under active development, it does seem to be getting maintenance uploads. [1] These days, however, web services seem to be moving towards a RESTful model with a JSON layer and there are plenty of JSON libraries on hackage, which you could just throw over the fastCGI bindings. Alternately you could try JSON over one of the really lightweight haskell web servers, such as shed [2] or lucu [3]. If you go the latter route, I'd love to hear how it went.
