Try this: Use Root Explorer and check if you see anything under /sd-ext. All I see is just the Parent folder. Now start at /mnt and go to /mnt/sd-ext. You should see your files on the microsd card. It seems to be missing the mount point just going to /sd-ext, but the files are there. All my pictures and music do show up in the gallery and music apps. Don't know why yours don't.
