Hi David

thanks for the info.

here is the plan:

1. I will release this one '08142011' as the next release since we have
    new gcc and kernel, all apps included in that image works fine.

2. after release I will rebase openwrt-xburst.git on top of last openwrt upstream

3. direct update our kernel to linux 3.0 or 3.1 maybe, no backport. :)

4. then find out what app not working. or all python stuff work again with new kernel

5. release one linux3.0/1 openwrt image as fast as possible. (have to include atBen stuff in this release)

I already lose upstream and late on release openwrt images. so I want speed up a little
  what do you think David. any advice will be great.
