However, it falls over while trying to load (unable to handle kernel paging request). My gut feeling says I've missed something in the kernel configuration step. Can someone please tell me the basic set of options required for a kernel to get the following system up and running?

 Why not base your config in the ubuntu config? 
 cp /boot/config-$(uname -r) path/to/kernelsource
 make oldconfig
