Indeed. I know I keep harping on about Fedora, but it's just the system I'm most familiar with; while emulators and various other potentially troublesome bits of software are excluded from the main distribution there's a very well supported effort at RPM Fusion that includes them, packaged in a way the integrates smoothly with the rest of the OS.

It may be that there's a need for a 'Maemo Fusion', but I expect it makes sense to wait and see for a little while first.
