On 2.6.5 this works fine (/usr/src/linux is read only and make mrproper'ed):

So what's new way of building external modules when sources are read only?

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.

Great but with 2.6.5 kernel (2.6.4, too. previous probably too) I was able to
build modules without need to build the full kernel.

This will start building kernel for me! I don't want that. I want only few
external modules to be built.
I'll wait for ,,next round of patches'' anyway.

not
make -C KERNELSRCDIR O=~/build M=$PWD modules ?

Would be nice if that ended in Documentation/modules.txt for example.

If you are interested, I will send you a brief Makefile for compiling external
modules. It works on a clean kernel source tree without compiling the whole
kernel.

With the patch that went into -rc2-mm1 there is no longer a need
to build the full kernel.
Previously kbuild required the Module.symvers file to be present,
but with the latest patch this requirement is relaxed.
