How does your distro autoload modules on booting?

I need a little information from people using different distributions for my Linux Kernel tutorial. Somebody asked me to include information on how the system knows which modules
to load when first starting up, and I thought it would be a simple matter, but the two distros on my HDD (Gentoo and SuSE) have different ways:

Gentoo uses a file /etc/modules.autoload which is simply a list of modules to load on booting.

SuSE keeps a line in its huge /etc/rc.config file for modules: INITRD_MODULES="modules list here"

Can people post how their distro manages this? If they're all very different, then at least the beginnings of a list of distros and their methods would be helpful for the tutorial

Well the filenames are different but basically it's a single file loaded at startup.

On Slack 8 I used rc.modules (use Gentoo now).

Thanks riv.

Can anyone else help out here? So far I've got info on Gentoo, Slackware, Mandrake and SuSE, but no others. I'd really like info on RedHat and Debian, as well as any other distros people use!

Debian uses /etc/modules, same syntax as Gentoo (rather, Gentoo uses the same syntax as Debian )

Thanks
