Actually, my mistake. -server does include CONFIG_XEN_PLATFORM_PCI
but
/lib/modules/3.0.0-12-server/kernel/drivers/xen/xen-platform-pci.ko
(at the very least) is not being built into the initrd for some
reason, even on the distributed version.

I somehow doubt the Phoronix guys built their own kernel.  That
would imply they were using emulated disks.
