Hmmm... direct from my experience Apple phased out Airport Utility 5.6 many OS updates ago. I have both 5.6 and 6.1 installed so I can control old firmware Airports as well as new. You shouldn't need any hacks or workarounds. You just need to download the old Airport Utility 5.6. While this had been the situation with the software since at least OS 10.6? I say this, after just setting an old 802.11g Airport Express Last week as well as Airport Express, 802.11n from the same computer running ML without problem.
