After attempting that very project recently, for a stripped-down
kernel used for an "appliance" linux system at work,  my impression is
that it's not possible to do this any more, at least on any system
setup to use udev. mkinitrd not only supplies modules for  hardware,
but also the initial /dev entries for console and other services
required at boot time. Most (or rh only?) systems that use udev have
an empy /dev structure, so the inital /dev entries have to be provided
somehow before udev is started.

You could try populating /dev with the required entries, but it's more
work than I wanted to do, so I just used mkinitrd for my project. Even
with sataand ide stuff builtin, I was not able to geta successful boot
without mkinitrd.

FYI, I wasn't even using LVM or RAID.

HTH,
