Separating the task_struct from the kernel stack is a change that was
made to all architectures earlier on in 2.5 development.  There is no
plan to do something similar in the 2.4 series since the 2.4 series is
now officially in maintenance mode.  (The OCP framework for PPC is
still being worked on in 2.4 but most other stuff should be pretty
much stabilized by now.)
