This will extract the source and apply patches under the BUILD directory.  You should be able to find a linux-2.6.18.i686 directory there that you can tar up, modify, and compile anyplace else.  I do this at work since we need to apply some patches to support some different platforms (like touchscreens, PCMCIA issues, etc).  The -bp does the "prep" stage, which extracts source and applies patches.
