I guess you have to configure (and perhaps build?) the linux kernel
under /projects/SensorNet/gumstix/gumstix-buildroot/build_arm_nofpu/linux-2.6.20gum
first. This will create config.h which is needed to build the kernel
module.

The robostix_drv.ko can be loaded from anywhere if you point insmod to
it. To load it automatically with /etc/modules I'm not sure, but
somewhere below /lib/modules/2.6.20gum

The executables can be anywhere, but it's convenient to have them in
your path - such as in /bin or /usr/bin.

For testing I keep all that stuff in /root/robostix and just run stuff
from there:

cd robostix
insmod robostix_drv.ko
uisp whatever  -or- i2c-load etc.
robostix reset off  <- this starts execution of the robostix code
