Yes, but I don't think it's of great importance. I'm just pleasing a
test with the simplest possible 1-line fix. Do you know of anything
that actually cares (i.e. not just "shows it to the user") about that
particular DMI field, and does something different if it reads "ECC"?
For that matter, hvmloader is already saying that the host is running at
some number of megahertz, which does not make sense for virtualization
because the host may be loaded and slow down the guest.
