Or, push the kernel (with included initramfs) out via netboot, and after 
mounting the root filesystem, copy the modules into place.  If you have a 
large number of modules (too big to fit inside the kernel image), push 
them with rsync (or similar) to the client machines, either from within 
the initramfs or with an initscript that starts before any others.

Never used tentakel, but IIRC there's another parallel-shell tools 
available that works over rsh/rlogin/ssh called psh.
