First: if you don’t know how to install and compile a kernel, don’t even start.
Second: openSUSE 11.2 is coming on 11th of November. It will include kernel 2.6.31. Rather wait for that, than getting stuck until then.
Third: if you’re ‘old enough’ on linux, you might go for a Milestone 7 install. The Milestone releases are for testing purposes only, and may contain serious bugs, but M7 has kernel 2.6.31 rc9 so if you really need that…
If you want to keep your distro in a “reliable” state, then don’t start updating software (especially such core components like kernel or your desktop environment) to non supported versions.
Your distributor takes care of security updates and bugfixes, if you start including your self-built stuff, you are the one who has to take care of that and should very well know what you are doing.
If you start including inofficial repositories containing newer but unsupported packages, you don’t have to take care of updates yourself but still should exactly know what you are doing.
As you ask for a “step by step” help, you obviously are still far away from being experienced enough to just start messing around with unsupported packages.

@Knurpht As we say in german “2 Dumme, ein Gedanke” (translated “Two stupid guys having the same thought”)
i tried yesterday the openSUSE 11.2 M7. Many many bugs… The YAST failed to open (i fixed that later) but generally it hadn’t repositories, many errors on update… I spent about 7 hours determing the problem… And now i chose to install openSUSE 11.1. But my laptop works better with latest kernel (example on Fedora 11, Ubuntu 9.04/8.10/8.04, Mandriva and Gentoo) So i just want to upgrate to the latest kernel. I know that i can keep my previous kernel so if something will go wrong i don’t have problem to boot from previous kernel or to re-format to openSUSE 11.1.
I read that if i add some repositories i can install the kernel… From online update? or from command line?
On other distros i’ve done that without problem… I’m not familiar to openSUSE… The strange “like-KDE” gnome panel etc etc… General all their software etc etc
I know how to compile kernel… But i want now just an easy install
For keeping the old kernel, use rpm in the command line (read also “man rpm” and don’t use -U but -i) or adjust your zypp.conf (not 100% sure if that will work, rpm will certainly).
Read the comments of my last post, if you don’t adjust your zypp.conf (don’t exactly know the option by heart atm), you will overwrite the installed kernel.
And use at your own risk, the more you add the more likely you will have to deal with conflicts, openSUSE has a lot more repositories than any other distro (thanks to OBS), many users packaging a lot of software in different versions, so it is impossible to avoid conflicts there, although there are not many, especially when sticking to only a few extra repos and using “well known” ones.
Holy cow, do you even read other users suggestions before answering?
With your “answer frequeny” of only one or at least less than five minutes, you certainly don’t manage to read them carefully, as you show by your answers.
