Cross-compiling Custom Kernels for Little Linux Plug Computers.
It covers how to find and install a cross-compiler (sadly, your Linux distro probably doesn't include one), configuring the Linux kernel build, and a few gotchas and things that I've found not to work reliably.
It took me a lot of trial and error to figure out some of this -- there are lots of howtos on the web but a lot of them skip the basic steps, like the syntax for the kernel's CROSS_COMPILE argument -- but you'll need it if you want to enable any unusual drivers like GPIO. So good luck, and have fun!
