It may well be useful to spend some time learning about the kernel
packaging stuff they do.  In the next release, there's a little easier
build system, half-documented at
https://wiki.ubuntu.com/KernelCustomBuild

The current Debian way as I understand it is to use kernel-pkg.
http://newbiedoc.sourceforge.net/system/kernel-pkg.html
This one's more Ubuntu-oriented, but don't follow it step-by-step (ignore
the part about setting a root password, for example)
http://doc.gwos.org/index.php/Kernel_Compilation_Dapper

In any event, you can certainly build your kernel external to the
packaging system, but it's nice to integrate everything together. 
Presumably, that information will get you close enough that you can learn
more Googling around than I could reasonably put in this posting... :)
