Oh, no, you are oh so wrong. you forgot all the modules .udeb, and they are
loads of them. Like waldi said, it was around 200 packages 6 month ago, and
probably over 400 today,

Nope. you have the 2.4 kernels and the 2.6 kernel, so you add the total number
of kernels which is between the number of arches and two time the number of
arches. Actually, you have to take every available flavours as you mentioned
above. On powerpc this is 5 for 2.4 kernels and 3 for 2.6 ones for a total of
8. (2.4 : powerpc, powerpc-small, power3, power4, apus, 2.6: powerpc, power3,
power4, soon to come ppc64 iserie-legacy, generic and generic-power4
additionally, and i have had at least one case where the UP kernel failed and
a SMP kernel is needed, so maybe we should double some of these).
This makes 8 powerpc flavours, And a quick look at :
http://packages.qa.debian.org/l/linux-kernel-di-powerpc-2.6.html
Will show you that powerpc has 114 .udebs, and the 2.4 kernels have 127. Mmm,
easier to get an idea on :
http://qa.debian.org/developer.php?login=debian-boot@lists.debian.org
So, for powerpc, this is already 241 .udeb packages, and it is only one arch
out of 11.
Do think become clearer now ? Or maybe i am missing something ?

The difference is between having (in the powerpc case) 114 .udebs in one
package and 127 in another, over having 241 in the conjunct package, which
breaks the packaging tool if i am not wrong.

You are welcome to look over the debian-boot archive though, but i belive
Colin, Joeyh and Waldi implemented the thing, so they would be the best to ask
about this, and since Colin works on ubuntu with you, he is the natural person
to ask, also see above about the problems in your calculation. Given the
powerpc packages, i believe even Waldi's 400 .udebs is grossly understated.
