You have to compile your modules against kernel source tree used to
compile the current kernel image running in you FR. In order to do
this you have to build the kernel image using the MokoMakefile (the
OpenMoko framework I mean) and change the kernel image and modules of
your FR.

On the other hand you can download the toolchain
( and compile your kernel (see
Advanced Topics) and modules, so you can to change the kernel and
modules of your FR.

The most important thing is to compile usb-video modules against the
kernel tree used for compile your current FR kernel image.
