You probably did and I missed it too. Good that you have those options, now:

What is the NIC you are using? Is it a Intel one? What does /proc/interrupts 
look like?
Can you send me the full domU output? What does the Xen hypervisor mapping look 
like
(xm debug-keys q, xm debug-keys Q, xm debug-keys i)? What is the motherboard 
you have?
Did you look up to see if there are any errate for the motherboard or the NIC 
you are using?
Do you have the latest firmware for the NIC and the latest BIOS for your 
motherboard?
Is the OpenWRT kernel you are using one that you built yourself or do they 
package it
for you? Can you try using a vaniall built one (2.6.37 vanilla is perfect).
Is this a 64-bit kernel or 32-bit? Can you try using a 64-bit one (you should be
able to run a 64-bit kernel alongside 32-bit userspace).
