I'm not sure if i have all the context of this email correct, if
you mean you want to port the patch I did for the x86_64 architecture
on the 2.6 kernel to 2.4 then its wrong-headed. There exists my
patch for the 2.4.25 kernel that Keith has in the 4.3 directory.

Is there some feature that it doesnt have you want? 

The code for 2.6 uses kernel hooks that are not in the 2.4 kernel,
if they were I would probably port back that code myself :)

The existing 2.4 patch could still be polished more I suppose but
its not like a port is needed.
