With the help of Manuel Bouyer I finally solved this one:

First I configure and compile the INSTALL kernel with the drivers I 
need and without those that give me troubles.

Next thing to do is to get a memory disk image: I go into 
/usr/src/distrib/<my-port>/floppies/ and do a 'make clean; make'. For 
some reason there is some error, which I ingore: I do one more 'make'. 
After some shuffling on the harddisk, make stops again with some error, 
but now, inside /usr/src/distrib/<my-port>/floppies/ramdisk there is a 
file caled ramdisk.fs, which contains my md-image.

Now I use mdsetimage(8) to put that image into the INSTALL kernel. Then 
I gzip the kernel and put the resulting netbsd.gz in the root of my 
custom CD.

At last I chose to build my own kernel for the system to use after 
installing. I cheated a bit and put this in the place sysinst expects 
the GENERIC kernel to be. This will make sysinst install my kernel 
instead of the GENERIC.

That's it. Good luck to anybody else who'll try this, and a big bunch 
of thanks to those who have helped me.
