If you go to http://edelivery.oracle.com/linux and pull down the source
cd for Oracle VM Server, you should find a pair of patches in the kernel
srpm that are exactly what you need to apply.  One is something like
"intel-e1000" and the other "intel-ich9".  Should apply cleanly.  The
distro is free to use if you'd rather do that.
