Always ALWAYS make sure you have your hard disk and root file system.
(This may seem obvious but going from a distribution's .config to a
hand-rolled kernel with make oldconfig can backfire if you don't also
make an initrd.)

Keyboard and Video also come to mind. Once you have that, you can
recover from a forgotten module by recompiling and rebooting. Obviously
a known-good kernel is good too.

There's nothing remarkable about it. All one has to do is hit the
right keys at the right time and the instrument plays itself.
