Sure, let's try that.  Maybe this is the better way to go anyways.  I just
learned that disabling iLo2 doesn't necessarily disable the management
firmware on the network device.

For this to be a meaningful test though, we need to verify that the
driver sign-on messages have a line that reads "ASF[0]" on eth1.  Can
you confirm?
