I also use linux, and I create tracks with the gpsies.com website. You can choose your favorite underlying map while creating a track (google terrain, Bing sattelite, OSM). Then I connect the Garmin device with the USB cable and upload the .gpx track to the GPX folder on the device.
To view the tracks I recorded with the garmin, I use marble on KDE. It would be cool if you could also use marble to create a track, but as far as I know that isn’t possible (yet?).
Hope this is helpful.
