How much time does it take to configure vanilla kernel to run with
fedora? Can you give me some guide or some general info.

I'm not willing to do this if it takes 5 hours just to see what
happens... if we can draw some mayor conclusion and if I can give some
valuable feedback then I have no problem doing this.

I still need some guide or some howto for making vanilla kernel work
with fedora.

I player with building kernels few years ago but I didn't do it since
them so I'm a bit rusted.

I was doing custome kernel building on suse and I know that suse has
some tools that make that process really easy - tools for copying
existing configuration to new kernel and others.
