MeeGo on netbook has not much in common with Maemo. So you cannot (or at least not easily) install Maemo software on the netbook.
The situation should be simpler with Qt-based Maemo software. x86 versions of the software from maemo-extras can be downloaded, but since the package format is different on MeeGo, you'd have to extract stuff by hand, and hunt down the dependencies by hand, too.
It's easier to get native Linux software running on a MeeGo netbook.
