Probably a good warning not to take everything written here as "gold" info...

For instance, to get notification sounds to work on my EVO, those "ringtone" etc folders need to be on the SD card under a folder structure like

/media/audio/notifications/
and
/media/audio/ringtones/

Not right at the root of the /sdcard/ folder.
