Comment 52 for bug 579276

You can test that too.

First install the tools
apt-get install dpkg-dev python-software-properties
After the tools are installed run
apt-add-repository ppa:kernel-ppa/ppa"
and then edit:
/etc/apt/sources.list.d/kernel-ppa-ppa-lucid.list
Copy this line
deb http://ppa.launchpad.net/kernel-ppa/ppa/ubuntu lucid main
and change the copy of the line to
deb-src http://ppa.launchpad.net/kernel-ppa/ppa/ubuntu lucid main
Run
apt-get update
Then run
apt-get source linux-image-2.6.38-2-server
that will pull down about 96 MB of kernel source package and unpack it via dpkg-source -x out to 578 MB total.

Then apply the patch and run
debuild -i -uc -us -b
to build the unsigned binary deb packages.
