Disabling sociable in teasers

This is more feature request then a support question. But first of all let me say “thank you” for the great plugin. Now, to my little problem:

As you can see on my site I have included the sociable plugin but have replaced the default icons with bigger ones (48×48):

And while this look great on the posts or if it is part of one of the featured posts, it looks pretty terrible in the teasers. Because of this I have currently switched sociable off completely on my home page (http://sm4good.com/) but ideally I would like it to show up in the featured posts and no in the teasers.

Thank you very much!
