Again I got no clear answer to the question asked, so I guess now it's fair 
to assume this must be the right place for discussion after all.

I've installed openSUSE 12.3. Its 3.7.10-1.16-default and server 1.13.2 
behave nicely. Beyond installing Mageia 3 to get 3.8.13 and 1.13.4, and as 
one who does not build software even via proxy, I'm open to suggestions how 
to get kernels and/or other xorg versions needed to perform bisection.
