Jason,
There are two different ways of netbooting on EFI-based systems.
EFI supports both PXE and regular DHCP. The client will first try PXE if
it fails, then it defaults to DHCP. Elilo supports both. However any
existing Linux (IA-32) PXE server WILL NOT WORK for IA-64 clients because
some special support is needed on the server side. None of that support
has made it into the official DHCP server as released by ISC (www.isc.org).
This server is the base for the one used by Redhat, for instance. Intel has
created a patch for it and it is still waiting for it to be integrated into
the main codebase. As such, the situation on the PXE side is not that good.
I have tested elilo with the patched version and I know it works, but it is
not available at this point. For now, I recommend using regular DHCP. This
works out of the box on existing IA-32 Redhat systems as you can see by
yourself now that your problem is fixed.
Your dhcpd.config can be as indicated by Alex.

Then elilo can download its configuation file, the kernel image and initrd
from the DHCP/TFTP server. For the configuration file, elilo will look for
a first match in the following order:
1) a client-specific file: AABBCCDD.conf where AABBCCDD is the
captilized hexadecimal representation of the IP address assigned
by the DHCP server. For instance, if the IP address is 15.4.89.69,
then the file must be 0F045945.conf.
2) an architecture-specific file: elilo-ia64.conf if the client is
an IA-64 machine. elilo-ia32.conf if coming from an IA-32 client.
3) a generic file: elilo.conf
Hope this helps.
