Bug#489058: 2.6.25-2-amd64: acpi_cpufreq won't load on Xeon E5420
Unfortunately, I'm no longer administering the system in question and
so don't have a Xeon cpu to test it out on. I still have access to the
machine, but it has been rolled back to 2.6.25 due to intermittent
soft lockups occuring in 2.6.26. I've been meaning to report these,
but I'm not sure if I really have enough useful information on what's
causing them.
