Can I use linux-source to rebuild the kernel for my CPU?

http://askubuntu.com – I've recently built a kernel for my Intel i7 basically using this guide modified to build the 3.5 kernel with patches from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-quantal/. This all worked fine, however, I noticed that the patch set in apt (3.5.0-22) is considerably newer than what I found on kernel.ubuntu.com for the 3.5 kernel. It seems the linux-source package should have what I need to build an i7 flavour of the exact same patch set, but how do I prepare it? Is it already patched, do I only need to copy "debian.master/" and "debian/" into the source directory? (HowTos)
