The only valid point I see for still using kernel 2.4 is
"never touch a running system".

But your ARM work seems to be new development.

If there are any problems preventing people from switching to kernel 2.6 
when deploying new systems (e.g. increased kernel size), we should get 
these problems reported and fixed in kernel 2.6.
