I agree with dan here. MeeGo the core OS with reference framework should most certainly be possible to get on the Samsung now that those drivers are open. Ganted youd have to figure out to flash it..

Right now the only closed components in MeeGo for the N900 is completely N900 specific.. drivers and modules just for this device.

Now.. getting Nokias other proprietary stuff that they plan to add in the future to MeeGo probably not.. But that's not part of the MeeGo core.. thats Nokia specific stuff. A community could add its own components to MeeGo to compensate.
