Yes, see my earlier mail with all the steps that I did, step 6.

dmesg output is pretty different when I boot directly with the kernel
and initrd copied on the dom0.

Remember, it's the same kernel/initrd, and without grub in between it
boots with all vcpus network and disk.

With grub in between, this at least does look suspicious:

[    0.032110] PCI: System does not support PCI

And yes, there are also no successful netfront lines.
