I have only experienced one problem and that is optimization of particular
inline assembly within ioports.c of arch/i386/kernel/. By replacing this
file with it's counterpart in a tree of 2.1.x, I am fully capable of
using a 2.0.x kernel (built with gcc 2.8.1) without any problem.
I have discussed this briefly with Alan on this list and he stated there
were to be other problems arising in my kernel from use of 2.8.1. However
I have yet to experience any other problems at all.
