So this patch:
f3fc28d52f42220bcce8c2fed12aef2a88c9fadc

    xen/pciback: revert the name of the PCI driver to 'pciback'.

should have done the trick but I am not seeing it in the
devel/xen-pciback-0.6.. Aha! I forgot to push the branch up to git.kernel.org.

Before I do that, can you cherry-pick that one please and tell
me if it works? If it does I will stick 'Reported-by' and 'Tested-by'
on the patch if you are OK with that.
