I built some fairly clumsy code to fix this on one of the blogs I run. It loaded the buttons in the footer of the page (so you can be reading the article before all the nonsense has loaded) then moves them to the correct places (the foot of the article) once ready. By the time you came to retweet or what have you, it was loaded.
It's not that dignified, but did what I needed it to do.
