There are bigger problems with 4xx support in 2.4 mainline than just 
missing some chips support.

Some parts which are already in 2.4 (e.g. ethernet driver) are of 
non-production quality. 

I can imagine Marcelo agreeing to commit 405GPr/405EP support as this 
change shouldn't break anything, but this will not make 2.4 support 
really useful for real world deployments. I think we are stuck with 
maintaining our own 2.4 trees with backports from 2.6. This is what I 
do myself of all our products (and yeah, diff between stock 2.4.32 and 
my internal version has already grown quite big to be acceptable for 
2.4 inclusion).
