I have uploaded a fcam-drivers package for kernel-power
http://n900.tannerlab.com/kernel/fca....5-1_armel.deb

There is nothing special about those modules. They just need to be compiled
against the kernel-power headers.
In the future we probably need a separate fcam-drivers-package (but AFAIK HAM is not sophisticated enough to handle such dependencies and conflicts) or we would need to add modules for both kernel versions to the fcam-drivers package.
