Well, the CentOS kernel is a 3.10 kernel in name (or number) only. Red
Hat backport much stuff from later kernels, and in this case that
includes much broken code for the Intel i915 driver. The code is broken
from around 3.15 and still not completely fixed in the current 4.0-rc6
code base. Updating to a newer kernel, and hence a newer i915 driver,
may or may not help, but it doesn't hurt to try.

No, they are two completely separate repositories:
