Do your remember Moblin? This project will now be integrated into Fedora Mini - the lightweight Linux distro targetted at Netbooks/Nettops.
"The Fedora Mini SIG is a group of Fedora contributors that are interested in Fedora on small devices" (like Netbooks & Nettops), as stated on the Fedora Project site.
Fedora Mini could be used to produce various spins for Gnome Mobile development/Intel's Moblin project.
The list of supported hardware is rapidly growing as you can see on this extensive list:
