Just to make sure on the same page - we're not talking about the theoretical ability to make things run on different hardware. We're talking about Nokia doing the backport of Maemo. Now, if they are reluctant to commit to a backport to something that uses a SoC from the same family (OMAP3), I would see zero chance of them committing to the level of effort a new kernel and driver port would require. And good kernel/driver support is a big deal in the embedded world, a running state is just half of the work, them comes power management, etc.
