Hmm, I thought that meant the domU kernel had to run the pcifront driver
plus the native driver for the PCI device.  Is that right or have I
missed something?

Is there a way to tell if the domU is actually running pcifront?  My
/boot/config-2.6.18-53.el5xen shows CONFIG_XEN_PCIDEV_FRONTEND=y, but is
there a way to verify that it is actually in the running kernel?
