I got it working, and it is really great. Thanks to all who are involved with this.
IMHO, the installation page should be modified as follows:
On the "e200rbootloader" page:
If there is no "USB settings" on the player, to get a player into MSC mode, select "Rhapsody" mode rather than "Plays for Sure"."
Under "Step 3":
"Some Linux systems may detect and mount the Sansa automatically. If so, then you can "drag and drop" files in the root directory or the system directory. However, be *SURE* to unmount the Sansa before disconnecting the Sansa. If you do an "eject" command, the files may not be written to the Sansa, and you will have problems ."
