Note that my suggestion about using the `N' flag for outb works also for
older versions of GCC, but will generate worse code (any constant will be
put into register edx before the instruction).

Therefore, you could tranquilly use it already now in the kernel.  The
generated code will improve as people upgrade to newer versions of GCC.
