Someone made a pretty interesting project -- ported flash from android to iOS4. For that they used jailbroken iPad(with Spirit). The project is available on github - http://github.com/comex/frash . The more detailed news are here - http://www.redmondpie.com/flash-on-apple-ipad-video/ with video demo. I hope it will help maybe to get the flash 10 on maemo5 as well
