I have found it useful to read the README file in the root of the kernel
sources tar file. It includes information about applying kernel patches.
Also, the file Documentation/Changes has things like minimum revisions
required for compiling and running a specific kernel.

It's a good idea to check out the makefile in the root (of the kernel
sources) as well. Set EXTRAVERSION on line 4 to something unique so you
don't overwrite any of your existing modules directories. I think the
install target still uses lilo by default, but I believe it gives you
the option of having your own installkernel script, and you may want to
uncomment where it sets INSTALL_PATH.

If you happen to be following the work of a specific developer because
of what you've read in lkml or elsewhere, you can usually find their
patches in /pub/linux/kernel/people on kernel.org.

Enjoy!
