    Cool stuff.  One question -- when you patch the kernel do you clear the
    68040's code cache?  I'm not sure exactly what that entails from user
    mode, but it's probably necessary.  Since the mods are being written as
    data, they are going into the data cache and not the code cache so if
    entries corresponding to those code locations exist in the code cache
    strange things will happen.  Since the 68040 uses a physical memory
    cache it is unlikely that the kernel is clearing it every context
    switch (which is good... you have to clear the cache every switch on an
    030 because the 030 has a VM cache).
