I'm having trouble passing 2 ethernet NICs to a DomU. I'm referencing:

The Dom0 kernel seems to be configured correctly. The pciback module is
compiled as built-in so I'm passing the pciback.hide on the kernel line
in grub.conf:
module /vmlinuz-2.6.16.28-xen0 root=/dev/md1
pciback.hide=(01:07.0)(01:07.1)
Output of dmesg:
Kernel command line: root=/dev/md1 pciback.hide=(01:07.0)(01:07.1)
...
pciback 0000:01:07.0: seizing device
pciback 0000:01:07.1: seizing device
...
So things seem to be working properly in Dom0.

Then I'm passing these 2 PCI devices (2 ports on an Intel PRO/1000 PCI-X
dual-port NIC) to the DomU. The NIC on the motherboard is connected to
the xenbr0 and we're passing that address in as well.
vif = [ 'bridge=xenbr0' ]
pci = [ '01:07.0', '01:07.1' ]
Here's output from dmesg in Dom0:

The e1000 driver is loaded as a module in the DomU kernel (using the
"e1000" line in modprobe.conf).
Have you tried adding this line do a domU's modprobe.conf?
"alias eth0 xennet"
