The way to build modules are now:

cd $KERNELSRCDIR
make
make clean

cd $MODULEDIR
make -C KERNELSRCDIR M=$PWD

This will work even with MODVERSIONING turned on.

There is currently a glitch that requires you to have defined
at least one module in the kernel. net/dummy for example.
When next round of patched are in you will not need to build the full kernel either.

If you do not want (cannot) build the kernel in the $KERNELSRCDIR
then you can use:

cd $KERNELSRCDIR
copy config-up ~/build
make O=~/build
make O=~/build clean

cd $MODULEDIR
make -C KERNELSRCDIR O=~/build M=$PWD


Hope this clarifies it.
