Dave,

please bear with me, I still don't get this.

We are talking about developers who by doing work on X 
(accidentally) break the API, right?
Those developers have already managed to build the Xserver 
and have takled the biggest hurdle, right?
What keeps anyone from using a simple script like the
one below to buildtest the drivers before they push
a patch that (potentially) breaks the API?
If we put a script like this in a convenient place and 
strongly encourage people to do this, why shouldn't this 
work?
Sure it takes some time to run, but most developers do
lunch at some time, don't they?

My point here is: we are trying to solve a social problem
by demodularization, not a technical one. The technical
problem is easy to solve (30 lines of script code and 
80 lines of driver list).
This is simple at least for the drivers. As Matthias has
pointed out API breakages happen elsewhere, too. Building
this dependecy chain is a lot harder and more time consuming.
Still we don't propose to demodularize the entire X.Org tree.

Cheers,
	Egbert.
