I'm trying to get this series to work -- i.e. get dream boot up-to
serial console. 

I tried applying series on 2.6.29, and it failed compilation.

On 2.6.30 and 2.6.32-rc, I get "Uncompressing linux..." feedback on
serial, but that's it. Do you still remember what kernel version these
should be applied to? .config would be helpful, too...
