   Thanks Alex, I see the problem...

elilo.conf:
append="console=vga console=tty1 console=ttyS1,19200 root=/dev/sda3
dom0_mem=1879M"

Boot log:
(XEN) Xen command line: 
...
Kernel command line: BOOT_IMAGE=scsi0:/EFI/gentoo/boot/xen.gz
console=vga console=tty1 console=ttyS1,19200 root=/dev/sda3
dom0_mem=1879M ro

For an ia64 system, the append line in elilo.conf is split as follows:

<xen options> -- <linux options>

I think you'll have better luck if you make your append line something
like:

append="dom0_mem=1879M -- root=/dev/sda3"

Let us know how that works.  Thanks,

        Alex
