Re: Looking for i915 build info
Thank you both for the information. I had wrongly assumed that i915_dri.so was a binary provided by Intel.

The clientside 3d module, i915_dri.so, is built from Mesa CVS, while the Device-Dependent X (DDX) driver, i810_drv.o, is built from X.org cvs. Believe me, it used to be even more complicated...
