Have you tried 'acpi_rsdp=0xbabfe014' instead of 'acpi_rsdp=babfe014'?

Do you have the kernel console output from the failed boot with these
settings?

Unfortunately, that doesn't help either. I don't see any output from
the failed boot. Without the acpi_rsdp option, the kernel starts
printing out messages as soon as xen.efi's output is finished
displaying. With acpi_rsdp, the screen clears after xen.efi's messages
scroll by and then nothing happens.
 

Also, I don't think 'video=vesa:off vga=normal' options make much sense
under EFI and Xen.

Thanks, I took those out. Those were added automatically by the
proprietary NVIDIA drivers and I copied them into the xen.efi config.

Cheers,
