Ok !
I found them they move to functions.php in 2.2
its moved.
Look inside wp-includes/functions.php starting at line 1426
Better still, you can set them up in wp-config.php, which avoids having to do them again next time you upgrade WordPress.
Oh yes !!
How to do this ?
Which code do you write in it ?
Put code like this:
$wpsmiliestrans = array(
':)' => 'smile.gif',
';-)' => 'wink.gif'
);
Substituting your own codes and file names, of course. Make sure there are single quotes around each code and each file name, and that there is a comma at the end of each line except the last.
Put it towards the end of the file, just before:
require_once(ABSPATH.'wp-settings.php');
?>
If you have a lot of custom smilies, it makes upgrading a little less awkward.
So, um, it appears SOME of the info from the links below, is still valid. And SOME of it needs to be updated for WP 2.2.

which links to this interesting resource on Taming Smilies, that explains more detail what LesBessant was saying,
