Booting DBAN from PXE failing with non-fatal errors

I have a functioning PXE configuration that allows to boot to an installation by Kickstart or rescue, both via RHEL6 media.

I'm trying to add DBAN to the mix to make for a more complete solution for our needs. I have it set up to boot and it will load, but it keeps failing with

DBAN finished with non-fatal errors.

 * ERROR /dev/sda (process crash)

Press and hold the power button to shutdown.

I can get it to load via CD without problem.

The PXE menu entry that I have is

label wipe
    kernel /images/dban/dban-226.bzi
    append initrd=/images/dban/dban-226.bzi root=/dev/ram0 init=rc

I've also tried without the root= or init= options with the same result.

I'm not even entirely sure about those options. Not much that I've found online gives much detail or explanation. One thing I know for sure, is that right now I don't want to enable the autonuke option. I simply want to load up the interactive method.

Has anyone been able to make this work?

EDIT: Potentially pertinent information
The server that I'm testing this on (and, in fact, 99% of our servers) are VMs running on VMware ESXi. The CD works when I attach it as an ISO to the VMware console and boot to it.
