I am lagging a bit on the -docs maillist backlog, will try and catchup 
over the next few days.

sounds good :)

I'd say no, not here in the user facing wiki

No, but there is a big open door in the c5plus kernel window. That would 
be the best place for this.

However, expanding a bit ( and this conversation might be better for 
-devel rather than -docs ).

Is the modified kernel the the only bit of change you need for i586 
support ? I'd think a glibc.i586 might be worth doing as well. And there 
were a few other packages that were required to be patched on c4 to make 
it work for i586. How many of those are needed here as well ?  And there 
are a lot of patches in the kernel tree that might not impact the i586 
code at all. eg. whats the state of xen in this i586 kernel ?

If there is reasonable interest in running a i586 tree, then imho, a SIG 
dedicated to this would be the best route to go. It would also make it 
possible to have a i586 specific tree that can be maintained in parallel 
to the main core distro.
