The feed dialog, in conjunction with FB.ui, is the new way to accomplish this when using the Javascript SDK. You should considering updating to the new SDK. At which point, you'd be able to display the share count of each url on your site by using Facebook's Graph API. Example Below.
Here is an object the graph API returns for google.com. Notice the total share count.
{
"id": "http://google.com",
"shares": 12265103,
"comments": 10121
}
If using something like jQuery, a simple GET request can retrieve the above JSON
var shareUrl = 'http://google.com';
var endpoint = 'http://graph.facebook.com/?id=';
var fbSharer = 'https://www.facebook.com/sharer/sharer.php?u=';
$.get(endpoint + shareUrl, function(data){
$('a[href="'+ fbSharer + shareUrl +'"] .count').text(data.shares);
});
Assuming some HTML like:
<a href="https://www.facebook.com/sharer/sharer.php?u=http://google.com">
<span class="count">0</span>
Share Me
</a>
