direct2d acceleration on FF4 causes really bad font rendering problems for my site. Text goes on to of each other and behind pictures making it impossible to read for some parts. Disabling HW acceleration fixes the problem. Is there a script that I could use to disable it automatically for my site?

Did you check if there is an update for your the graphics display card driver available?

Hardware acceleration shouldn't cause such problems in general.

In fact updating my graphics was the cause of the problem. With the old drivers there were no problems. It depends on the system. So far I've tested on 6 Windows PC's. on 2 of them it worked fine. My site should be 100% W3C compliant. It works fine on 3.6, Chrome, IE and Opera

I have further narrowed down the problem. It only occurs when using font size 11 or bigger. 10 and smaller all seem to work ok. Only tested with Arial so far.
