--In an effort to get kernel modules to compile properly on Gumstix (via how-to located at http://gumstix.8.x6.nabble.com/Linaro-linux-source-has-no-makefiles-help-td4967421.html, Larry Martin 21Jun13), tried the following:
     #apt-get install devscripts
     #apt-get install fakeroot build-essential kexec-tools kernel-wedge
     #apt-get build-dep linux
     #apt-get install git-core libncurses5 libncurses5-dev libelf-dev asciidoc binutils-dev
     --in ~/build/linux-omap-3.5:
     backup .config file
     #make mrproper
     #cp /path/to/config-backup .config
     #make prepare
     #make scripts
     #make && make modules_install (left running over the weekend)
