Your findings reflect my experience - there isn't much out there and what is basic or doesn't work at all.
Link Sailor is another http://linksailor.com but I suspect not actively maintained (developed by Ian Davis when he was at Talis doing linked data work)

I think the Graphite based browser from Southampton *does* support content-negotiation - what makes you think it doesn't?
