Ben,

you're almost there.  Get the binary firmware from 
ftp://ftp.qlogic.com/outgoing/linux/firmware (just get the .bin files, not 
the .bin-version files).  There are five or six files altogether.  You don't 
need all, but they are relatively small so it's no big deal putting all of 
them in /lib/firmware.

Make sure on the initramfs you have /etc/udev/rules.d/ with appropriate rules, 
including one to handle firmware loading.  Also make sure you have on the 
initramfs /lib/udev/firmware.sh.  This script is part of udev.  Just copy it.

Then recreate the cpio.gz and try again.  My guess is you forgot to include 
the actual firmware.  But you're getting very close to a working system :-)

Oh and last but far from least, you need a working /init script on the 
initramfs.  All it needs to do is mount /proc, /sys, /dev as a tmpfs, start 
udev, mount the actual rootfs device (as per your silo.conf) and switch_root.
