You can analize my initrd that do what you want at:

This version of Gentoo Live DVD, allows you to do that, and plus reasemble the
main ISO with your packages, in a few weeks may be we are going to release a
fully XGL supported version, I use to carrie my home files and system on my
20GB Hard Drive to everywhere :D.
If you don't want the system, just download the small boot iso (about 35MB) to
get the name of the drivers, the proper order, and the retries and wait time
before to guess there is no USB Hard Drive.
If the BIOS is supporting to boot from USB, probably the Drive will being
setle before loading initrd (when bios init code finish), but if not, you
should wait when loading the drivers, cause the drive needs to setle before
scanning, mounting or doing I/O over them, if you just load the drivers and
try to mount, you are too likely to have a race condition.
Using ISOLinux hardcoded for GFXBoot, but the config and initrd should be the
same.
