These are pretty standard msgs if the kernel doesn't see the passthrough 
device. The standard F8 xen kernel has CONFIG_XEN_PCIDEV_FRONTEND=y, and thus 
is built in, not a module. (You'll notice this setting is completely missing 
in F9 :-(  ). Make sure that your domu config has a line of the form 
pci=[ '0000:0b:00.0' ], and that on startup of the domu, you see 
in /var/log/messages a line of the form:

Jun 14 13:05:15 Insp6400 kernel: pciback: vpci: 0000:0b:00.0: assign to 
virtual slot 0

and in dom0, the directory /sys/bus/pci/drivers/pciback has a link named after 
your device id.
