The kernel in the android source dir isn't of much use. You'll want to check out the kernel tree separately. I did the following:
$ git clone git://android.git.kernel.org/kernel/common.git $ git checkout -t origin/android-goldfish-2.6.27 -b goldfish $ cd common # the kernel source is now in here $ make goldfish_defconfig Then build it and run it. If that doesn't work for you, you may need to get the config from a running kernel, rather than using the goldfish_defconfig. Use something like 'adp pull /proc/config.gz', decompress config.gz, and rename it .config in the kernel source directory. Then build and run it.
