I usually use /usr/src to put kernel sources (and some other for module,
well not always :o )

For example on my laptop which needs unichrome and at least 2.6.11 for
i2c and fan control, I have installed several months ago a Kaella
(french lang Knoppix version from linux-azur.org) wich had a 2.4.24 kernel.

I made lot of config to be able to have fan/temp control, I extracted
2.6.11 kernel sources in /usr/src and change sysmlink /usr/src/linux.

So that you could test different sources, just in changing your symlink(s).

Don't know in what suse source differ but you can use source from
kernel.org.

You could probably edit Makefile.

I do like that.

vmlinuz should point to your config by default.

I am a newbie so and think I will be forever in front of this enormous
community work :)

Hope it will help !
