Official .config file for Ubuntu Kernel packages

[Jochen Roemling]

Hello,

after I've seen that the bcm43xx module in the Ubuntu Kernel tree 
published at kernel.org/git has been significantly updated, I was 
planning to build a bleeding-edge kernel to test if it still freezes 
when activating the interface on my Dell Latitude D800.

Cloning the git tree is no problem, but I don't have the official 
.config file that is used by the kernel team when creating the packages 
that can later be found on archives.ubuntu.com.

I have found a .config file in the linux-headers package, but there 
should be an easier way.
Where can I find the .config file that is used in the official builds?
Or is there some make <whatever> option in the Ubuntu tree?

Thanks for the info, please cc me on reply

Jochen
