I guess you figured it out :)

There's more on the initrd that just SCSI these days. Not sure why ext3 
isn't builtin, but that's Red Hat's choice.

That might also be software RAID/LVM too, those drivers are also modules 
on the initrd.

You can look at the initrd, see what's there, and decide what you are 
using from that.

cp /boot/initrd-2.4.20<some thing>.img /tmp/initrd.img.gz
gunzip /tmp/initrd.img.gz
mount -o loop /tmp/initrd.img /initrd
grep insmod /initrd/linuxrc


(don't forget to unmount /initrd and delete /tmp/initrd.img when you're 
done :) )
