11. Use of Contributor Credits: You may not market or advertise the Open Game Content using the name of any Contributor unless You have written permission from the Contributor to do so.
OK, either you're reading something that isn't there, or you're gonna have to spell it out for me. The parts you quoted, and particularly the bit you emphasized, seem to support my position, not yours. You specifically bolded the bit that says you can't indicate compatibility or co-adaptability with any [registered] trademark. It doesn't say anything about indicating compatibility or co-adaptability with anything else--just trademarks. [It also says you can't use PI, but that's a blanket prohibition--the bit about compatibility is just emphasis.] Nothing in clause 7 says you can't say "compatible with Dynasties & Demagogues" [i just checked--the title isn't designated as PI, nor trademarked].
Now, on to the next bit: it says you can't use someone's name to market or advertise; it doesn't say you can't use someone's name. Marketing and advertising are not the sum total of things you can say within or about a work. Nothing in clause 11 prevents you from footnoting some text with a contributor's name (though clause 7 could stop you if the name were PI).
