Not needed.

Not needed.

Not needed, unless you want backup copies or something. You don't need the
kernel-headers package either, that's for other uses, not compiling a kernel.

Ok.

Or just symlink linux -> kernel-source-x.x.x

Ok.

Nope.
fakeroot make-kpkg --revision=3:local.kernel.version.1.0 kernel_image
fakeroot make-kpkg modules_image
(or something to that effect. Read the /usr/share/doc/kernel-package stuff
to get the right way)

Nope. Just dpkg -i the debs generated by make-kpkg in the /usr/src directory.
> 14. Copy /usr/src/linux/System.map to /boot/System.map
Not needed.

This is some crap with the timestamps and limitiations of depmod, I think.
Run depmod -a as root to fix. Or just ignore it.

Edit the kernel main makefile in /usr/src/linux/Makefile, look for CC=, and
change gcc to gcc272.
