Ah, great!

Well, I think source control systems do an ok job of showing files you've 
modified. :) As for the repository size, users will have to download a full 
Linux tree anyways...

Given the convenience of having a separate tree, and since the x86 trees will 
be separate soon(ish), I guess we will avoid a new sparse tree for PPC work.
