[Dri-users] Relationship between X 4.3 and DRI?

[Geoff <cap...@ya...>]

Hello,

As will soon become very obvious, I don't follow X/dri
developments very closely.  I am sorry, thefore, if my
questions seem terminally dumb, but here goes.

I am currently running X v.4.2 which I compiled
last September for the linux from scratch
installation I was then building.  At the same time I
compiled and installed the CVS version of dri. 
Everything has worked perfectly.

I want upgrade to X v.4.3 and to install a radeon 9200 card
(yet to be bought), in place of my present mga. I understand
that this card is supported under dri.

Looking to the current linux from scratch docs for guidance,
it seems to me that things have changed, so that dri is now
integral with X, and there is no need to install it
separately.  On the other hand, I note that it is still
possible to download dri from its own cvs independently of
X.

I have, in fact, d/ld and compiled both X v.4.3 and dri/cvs
just to prove that I can - but I have not installed either. 
I note that the dri compilation concludes with the
announcement that I have compiled X v.4.3.

I am confused.  Can someone please explain what,
if anything, is the difference between X v.4.3 and the cvs
version of dri?  Will both give me working drivers for the
radeon 9200?  Any other hints or tips?
