First, check that it's due to someone using an old version, and not just a
tile that hasn't been updated since the last renderer change.
Right-click, "view image" on any tile, then add a "_details" to the end of the
URL to see who created it and when.
e.g.
http://dev.openstreetmap.org/~ojw/Tiles/tile.php/15/16287/10807.png_details
If particular tiles are out-of-date, you can ask for them to be updated:

Same as if you uploaded hello.jpg as a tile in the middle of london - we
disable the account used to upload those tiles, and request a re-render of
any areas that account has contributed to.
The reason we haven't done that for people with out-of-date renderers yet is
(a) it's not a very nice way to treat people who are contributing to the
project, and (b) tiles at home doesn't give them a proper error message when
upload fails, so they may not even be aware that their computers' work has
been discarded.
I'd suggest just emailing people with old renderers asking them to update at
the moment, rather than blocking them completely.
Use the "_details" trick above to see who created the tile -- most of the
usernames are easy to match with regular people on IRC or the mailing list,
and there's some more info for finding people on
wiki.openstreetmap.org/index.php/Tiles%40home/Credits

In progress. Some of the clients are already reporting version-identifiers
(see them at http://dev.openstreetmap.org/~ojw/Log/Messages/ ) - and it will
be relatively easy for the server to not speak with old clients if we decide
that's what we want to enforce.
