For starters, you would really want to recompile your kernel, and disable
everything you don't need, such as PS/2-mice, USB, networking etc. When
you've done that, you should check out the "/etc/rc*.d"-directories, as well
as the "etc/init.d"-directory and remove the files that start the various
daemons/services you don't want. Of course, a better idea is to completely
uninstall all the stuff you don't want, and it should (really) stop loading
at the boot-process.

Debian is a good distro for minimal installs, so if you're stuck with a
bloated system, i would really advice you to format the drive and do a fresh
install, ignoring all the OpenSSH's, Sendmail's, Lynx's and such, which you
wouldn't want. I'm sure you'd get away with a relatively small install,
providing you with more space for your MP3's and OGG's :)

Good luck. Let's hope you get it working as you want.
