Dapper LiveCD: use custom kernel

What are the reasons the stock kernel is not usable for you?
 It's
certainly possible to replace the kernel, but it does
require a bit of
fiddling, in addition to rebuilding the live image itself.

We have a modified version of the kernel to add and change
processes
schedulers dynamically (http://www.emn.fr/x-in
fo/bossa). The LiveCD is
for cs courses and demo.

I already found some hints for my problem (thx Kamion on
irc):

- install your customised kernel and the casper package on
your
development                system
- update-initramfs -u
- dump the kernel and initrd from /boot/ into       
/casper/filesystem.{vmlinuz,initrd.gz} on the CD

I didn't test yet, but it seems like the udebs are generated
automagically.
