Which comes round to the main reason I'm doing this work (port the platform to 
2.6): if we are not using the *latest* kernel with the *latest* build/user 
tools, then we cannot share our work. Patches to an old kernel/gcc may 
probably get discarded when moving to the next version.

Nevertheless, I think my problem has been the binutils. After switching to 
version 2.16.1, the oops probability (per reset) dropped from 80% to <20% and 
the oops is less random. (that is, there is also one, real, bug)
