If I read the code correctly, make oldconfig will not use the config from /boot/, but just but just use a default configuration in case you don't have a .config in your build directory. So from my (limited) experience you would first need to do a cp /boot/config*`uname -r` ~/linux-2.6.39.1-install/.config Another option is make localmodconfig, which includes all the modules that are loaded into the new configuration.
