How can I install a newer kernel?

view full story

http://askubuntu.com – I'm running the current stable Ubuntu version (Oneiric) but have issues with the shipped kernel. Newer kernel versions seem to have fixed it, but the kernel-ppa/ppa does not contain the most recent kernel which is why I want to install the kernel from the next stable version (Precise). I also have have Virtual Box installed which also need to work in the new kernel so the "kernel headers" have to be upgraded as well. How am I supposed to install the kernel packages from the next stable version (Precise) without upgrading all other packages? (HowTos)
