For example: what does /etc/modules.conf look like. The answer is
*probably* there. And what *other* kernel parameters are listed in your
grub configuration file? Maybe include a copy of your grub config file
I'm wondering: does your system have an IDE CD-R/RW or IDE DVD-RW/RAM
drive? Most (all?) new computers have one or the other (if not both).
One likely thing is that the Debian 3.0 installer also included the
kernel options to use SCSI emulation for your IDE CD-R/RW or IDE
DVD-RW/RAM drive, which means you need some of the SCSI modules, along
with the SCSI-IDE emulation module. These are probably referenced in
the /etc/modules.conf and are needed when the kernel boots up and deals
with the IDE CD-RW or IDE DVD-RW/RAM. You can eliminate this
dependency (and thus skip the need for an initrd) if you never, ever
want to burn CD-Rs, etc. Linux's CD/DVD burning software is written to
deal with *SCSI* CD/DVD-R/RW/RAM drives and uses the SCSI-IDE to work
with IDE drives.
It is generally not a good idea to randomly second guess what the
*modern* Linux installers are doing for you. Unless you really, really
know what is really, really going on. If the installer thinks you need
an initrd, you probably do.
