It doesn't have to. For the directory shown this is
probably just because the filesystem was created by
root. I mount removable devices manually, and owner-
ship (as stored on the disk being mounted) is always
preserved. The permissions on the mount point itself
don't seem to matter.

If KDE's automounter is actually changing ownership
that's sort of 'evil' IMHO.
