I had a look at this over the weekend. I managed to get a userland
compiled with the current abi into single user mode on a kernel
compiled with -mabi=aapcs-linux (gnueabi). The main problem I found
was the change in packing for structs causing strange behaviour in
userland.

My plan is to clean up the code and post it somewhere for further
testing.
