Yes, I have found this with the Ubuntu LiveCDs as well. I ended up
extracting the contents and pointing them to an nfsroot, which does
not help with USB booting. Here is the stanza that worked, for what it
is worth: 

LABEL saucy-gui
        kernel ubuntu/saucy/i386-gui/vmlinuz
        append ro boot=casper only-ubiquity netboot=nfs
          nfsroot=172.26.107.3:/home/ftp/ubuntu/saucy/i386/
          initrd=ubuntu/saucy/i386-gui/initrd.lz quiet splash --
(the "append" line should all be one line)


The memdisk method works well for installer-only ISOs and a few other
(usually DOS-based) live CDs. I guess I should have been more explicit
about this in my earlier response.

What happens now? How do things work with your two-USB solution?
