   Can someone enlighten me as to what is the license of R200 Mesa
driver ? Also, what is the usual (accepted, preferred, etc..) license
for a Mesa driver code ?



Taken a look at the top of any the files in src/mesa/drivers/dri/r200? Here's what's there:

/* $XFree86: xc/lib/GL/mesa/src/drv/r200/r200_lock.c,v 1.1 2002/10/30

Basically the standard license for the Mesa drivers is the part from here down, plus a copyright line as above, with whoever you want as the copyright holder.


So is it XFree86 license ? Pre or post 4.4.0 ? Or something else ?

I would recommend avoiding confusion, and not using the name "XFree86 license" unless refering specifically to the XFree86 project. When refering to the XFree86 project's license, it is also best to indicate what specific version of the license you're refering to, as the older license was more or less "MIT style", while the newer one has additional restrictions.

"MIT/X11 License" is the traditional X license which most of the xc/*
codebase is licensed under, including most drivers, etc.  If adding a
new driver to the tree, please license it MIT/X11.
