Yes. the kernel-devel rpm has to be made available on the server side
along with cgi-scripts that can do the magic of generating new rpms on 
demand.

True. But DKMS solves a different set of problems. In my case I dont
have source rpms, but only binary drivers packaged in rpms in a
repository.
And the requirement is ability to automatically provide rpms for all
future kernels.

I imagine this dynamic-repository idea can be used with dkms on the
server side. Because dkms can generate rpms on the server on-demand
using the driver sources.(offcourse you would need kernel-devel rpm on
the server side too).
