EDIT: Use the -bc switch of rpmbuild:
-bc Do the "%build" stage from the spec file (after doing the %prep stage).
This generally involves the equivalent of a "make".
... since -bp will just unpack the "sources" related to the .rpm, but will not "make" them - which involves applying the specific SUSE patches... My attempt to use rpmbuild -bp is left below for reference - not that it, on its own, doesn't even extract the linux sources. Below is the log of using rpmbuild -bc, which both unpacks vanilla sources and applies patches to them (which can be seen from the terminal log, which has been left out here; note also that the patched sources will be in "BUILDROOT"):

Ok, this turned out to be quite convoluted (given I still don't know the proper way to do this), but the post How to compile custom kernel on Centos/Xen or optimize CS:S server showed the way. Following that post, I did this ( still in the kernel-source-2.6.31.14/
directory as in the OP ):

# ?? no linux sources?
... and, surprisingly, after all this, I still couldn't see any linux sources? However, I did notice that -e /path/to/kernel-source-2.6.31.14/rpmbuild/SOURCES/linux-2.6.31.tar.bz2 in the script above; and guessing that the linux*.tar.bz2 probably didn't get unpacked (there was nothing after the Symbol(s): line in the original output for the snippet above); I basically repeated what the rpmbuild tmp script did:

Well.. finally, those are linux source files I can recognize :)
However, those are still, seemingly, the "vanilla" 'unpatched' sources - I guess there is a command that does all this along with patching, but I'm at loss as to what it is... Anyways, hope this may also help others a bit - cheers!
