Also keep in mind that Apple, for some reason, doesn't allow 3rd party-non-thunderbolt-displays chained directly after their own Thunderbolt Display. However it will work if another thunderbolt-device is ...

Yes - add a Mini DisplayPort port to your iMac. Should only take an engineer and a machine shop to accomplish. In all seriousness, the mini-DVI port on your iMac is an output-only port, whereas the Thunderbolt/Mini DisplayPort ports also accept input.
