Compiling modules in kernel tree is like compiling kernel. Just install 
kernel-source-2.6.16 in arm scratchbox target,  go to 
/usr/src/kernel-source-2.6.16 and do it the same way like any other kernel.

enable your stuff

Then find modules (.ko) manually in kernel tree or do 'make 
modules_install' and find it in /lib. Kernel is in arch/arm/boot/zImage

No debian stuff neeeded except installing the source.

I find this easier.

Maybe there are still problems with linking curses when making make 
menuconfig. It is in list archives. I think it is just changing one line 
in Makefile somewhere. Ask if you can't find it.

Later found that better is to get 
http://www.kernel.org/pub/linux/kernel/v2.6/patch-2.6.16.27.gz
and patch the kernel. You get EXTRAVERSION plus .27 bugfixes. It applies 
almost fine. There are no arm specific fixes that would conflict with 
omap1 so it is easy. I think I got only one harmless reject in 
drivers/mtd/nand/Kconfig.
