Comment 9 for bug 1098302

Yes, that would probably do just fine. Raring is using the 3.8 kernel,
yes? I have been building 3.8 kernels for some of my 12.04 deploys, and
with few exceptions it has worked well, as it has the necessary fix. So,
if Raring is on 3.8, the enablement stack would work for me. Thanks!
