Debian definitely *does* change *some* kernel code:
"The source from which the Debian binary kernels are built is obtained
by taking the source from linux_version.orig.tar.xz (that is, pristine
kernel source with problematic parts removed) and applying a set of
Debian patches. These patches typically implement essential fixes for
serious bugs and security holes. The Debian version of the kernel
packages has the form version-revision where version is the upstream
version of the kernel (like 3.2.20) and revision determines the
patchlevel. For example, the packages with version 3.2.20-1 are built
from the linux_3.2.20.orig.tar.xz source, patched up to patchlevel.
Certain packages include extra 'featuresets' not included in the
upstream source, such as rt."

I don't think this is quite true; while there is an explicit
preference for patches that have already been accepted upstream, it
seems that this is not a rigid rule:
