Yes. Notice that the 2009.11 release is out now, and it has a somewhat
different (simpler) build directory layout.

Yes, if you need to patch something in the package sources, you'll need
to make a patch (quilt is nice for this) and copy it to
package/<something>/. Make sure you name it <something>-*.patch
otherwise it won't be applied.

What exactly is it that you are changing? If you're fixing something
general, then please submit those patches to the package upstream and us
so we can integrate it into buildroot.

 Mike> Is this the right flow?? Are there any instructions or tools to help do this?

It is, but it's pretty uncommon to have to do project specific patching
of the packages.
