NO!
It means it won't contain those improvements which were applied to have
the kernel work more efficiently on Core2Duo CPUs.
As you wrote before currently you are running 2.6.26-2-686 which is a
generic unoptimized (optimized for the generic 686 arch) kernel,
generally all distribution kernels fall into this category (they aren't
optimized for your particular hardware).
