I'm using WhiteRussian from svn and I need some kernel modules for which there are no packages. Can I do something similar to "make kernel_menuconfig" from Kamikaze?

I've tried the following steps:
- cd build_mipsel/linux-2.4-brcm/linux-2.4.30/
- make ARCH=mips menuconfig
- checked the necessary options from the menu (as modules)
  * br2684
  * speedtch
- make ARCH=mips

But I can't find the corresponding .o files for speedtouch driver although it is selected in the config file:

radu@akira /mnt/hdd1/apps_cvs/whiterussian/build_mipsel/linux-2.4-brcm/linux-2.4.30 $ cat .config | grep SPEED
CONFIG_USB_SPEEDTOUCH=m

radu@akira /mnt/hdd1/apps_cvs/whiterussian/build_mipsel/linux-2.4-brcm/linux-2.4.30 $ find . -iname speedtch.o

Why is this happening?
