Yes. If you look under the "Revisions" tab on that page, you will see a list of 
the revisions. Numbers 311-313 cover the changes in 3D acceleration. For each 
such revision, the "Files changed" link shows the diffs for the files.

Our setup installs vboxvideo_drv.so and uses it.

Just deleting the SONAME lines did not work for me.

Is it working for KDE with Plasma 5?

Attached. The changes are minor. A few routines need added includes, and 
set_task_state() has been removed. Fortunately, the latter is easily fixed with 
set_task_state(pSelf, ...) => set_current_state(...).

The openSUSE installation in a VM already installs the guest packages. As for 
testing with new compilers and kernels, I do the test builds locally and keep 
the VB package updated. My biggest problem is holding the update long enough for 
critical changes to propagate through the build process and get included in an 
update. If I submit too soon, then the current build task is superseded before 
it ever gets to the user and we start the process over again.
