Oh, it's unfortunate to hear that.  May I ask why it won't ever be in

I could find it useful to be able to test some changes locally on the  
simulator before deploying the kernel to the PS3.  You surely know  
that changes to the kernel often don't work on the first try ;-)

Aha.  I find it much more comfortable to work against a SCM (whatever  
it is) rather than against an extracted tarball.  Way easier to get  
the latest code, revert changes, see what has changed in the tree,  
extract diffs, and, with a distributed system such as git, keep  
history for local development until the changes can be published  
(plus when they are released, all the history is kept) or easily  
distribute these custom sources among multiple local machines.  So  
summarizing, yes, it'd be nice to have your cell-2.6 branch in synch :-)

I'll check quilt though.  Might be good enough for some other use cases.
