oms2go is a nice little openstreetmap editor that was designed for the maemo platform. I managed to install it on moblin too.

sudo yum install subversion gcc libtool libcurl-devel libsoup-devel gtk-doc make gnome-vfs-devel libgnome-devel gtk2-devel
svn co http://svn.gnome.org/svn/goocanvas/trunk/ goocanvas
svn co https://garage.maemo.org/svn/osm2go/branches/ports/debian osm2go

#first compile goocanvas
cd goocanvas
./autogen.sh
./configure --prefix=/usr
make
sudo make install
cd ..
#osm2go
cd osm2go
./configure
make
sudo make install
cd ..
#Finished. You can issue osm2go to start!
