I had the same problem as all of you, and I solved it in the following manner. This does break a certain tool, mostly the disable tool, although that never worked for me anyway.
Open up the Sociable.php, and remove the following lines of code:
if (get_post_meta($post->ID,'_sociableoff',true)) {
return "";
}
This makes Sociable stop checking if it should be on or off.
I am implementing Sociable manually, by inserting the code myself, I dont know how this will play if you are using the automated insertion.
I am using Wordpress 2.7 or so, Sociable seems almost completely broken for me, but with the manual insertion, and removing this line of code. I have everything I need.
