That would be better to have only one reference for the INTEL 32b arch. Actually we have i686 and i363, depending on the release and/or build.
We need to check if we can't use only one reference, and see with the releng why they name them differently for each release..
Since a few releases the naming has not been changed any more, and releng will keep this naming. We have i386/ directories and checksum files, while images are i686.
I think we could close this as wontfix, there is not much we can do and actually it's not more a problem, websites works fine with this kind of naming :)
