I've compiled kernels the non-debian way without kernel-package so my
advice below is probably not the 'right way' to do it...  :)

The modules you list in /etc/modules get loaded at boot.

Not sure what it does exactly... something to do with giving the kernel
an idea about compiled modules maybe.  I copy it to
/boot/System.map-KERNEL-VERSION

I don't use this package if I've compiled my own kernel.

to avoid this I edit Makefile and put something in `EXTRAVERSION =`
