Difficult? No, actually the process is fairly entertaining.

I think you're correct that RH applies a lot of kernel patches, but I've 
never bothered. If they're really needed, then Linus would have pulled 
them into the "standard" kernel. For a simple desktop box the standard 
kernel works just fine. I'm sure you can find some nice kernel building 
instructions on the web. I just download the kernel.org kernel and 
latest patch file, untar, patch, run "make oldconfig", "make", "make 
modules_install" and "make install". Cross fingers and reboot. Usually 
it works fine. I keep the latest Fedora kernel to boot from if the new 
one fails. It hasn't failed in a long time.

The hard part is getting a working kernel .config file. You can start 
with the Fedora config file (found in /boot), copy it into your kernel 
source directory, rename it ".config" and run "make menuconfig" to 
customize it. Be prepared to config / build / boot several times until 
you get it right. Remember that the Fedora/RH kernels are built to run 
on every hardware configuration imaginable. You can save some kernel 
memory and disk space by omitting all the modules for hardware that you 
don't have. There isn't any point in building your own kernel if you 
just use the Fedora config file. Experiment, break something!

You can also help everyone by testing the latest development kernels and 
reporting bugs. If you want to get into this, you need to subscribe to 
the kernel developers mailing list, linux-kernel at vger.kernel.org. Just 
don't post anything stupid because those guys tend to be less friendly 
than everyone here on the Fedora list.

Regards,

John
