Comment 7 for bug 309512

You would first have to selectively update the kernel (linux-image) adn linux-restricted-modules like described on the wiki page (Selective upgrading from intrepid-proposed). If the PPA sources are in the apt sources at the same time I would expect that the PPA kernel will immediately replace the one offered by -proposed. Hm, actually there is an update comming up so, if you updated and got a kernel without smb in the output from /cat/proc/version_signature, you can download the package here http://ppa.launchpad.net/stefan-bader-canonical/ubuntu/pool/main/l/linux/linux-image-2.6.27-11-server_2.6.27-11.23smb5_i386.deb and install it wit dpkg.
