I have tried downgrading to Intel driver in Intrepid by (forcibly) replacing it with the Hardy package.
If you do this, X will refuse to start because the older driver was compiled against a different version of X and depends on certain ABI calls that have since been removed; consequently X won't start.
I guess one could compile the old driver against the new X and hence backport it if one is really interested.
