I have the matching headers for sure. I just did "make reload" as in the 
instructions. I could try making my own list of modules and doing the 
remove/load manually. I didn't want to install them in case they didn't 
load properly.


    How to build the v4l-dvb kernel modules

The v4l-dvb tree is backwards compatable against recent vanilla kernels. 
Kernel version 2.6.10 or later is required to build the dvb modules, and 
version 2.6.12 or later is required to build support for hybrid devices.

   1. Change into the v4l-dvb directory:

      cd v4l-dvb

   2. Build the modules:

      make

   3. Install the modules:

      make install

   4. If you get errors in relation to unresolved symbols, please try to
      reboot before filing an error report.

    * To clean the source tree:

      make clean

    * To clean the build configuration:

      make distclean

    * To remove (rmmod) all modules at once from the running kernel (in
      memory):

      make unload

    * To insert (insmod) all modules at once into the running kernel,
      without the need to install them:

      make load

    * To perform the two commands above in a single step:

      make reload
