Do not use ondemand per default on opterons
This one should be a safe way to use performance governor per default on
opterons (It's switched to ondemand later via userspace tools).
Blacklisting could be done more clever (e.g. all smp AMDs without fire and
forget or similar).
I think we should not add it that late, because of one bug report (I still
couldn't run again into a machine hang yet) and it wouldn't help for this
specific machine anyway.
Even if the dead lock condition is found and a possible fix, modifing the
complicated rw semaphore code paths, this is nothing we want in RC3 or an
update... If this got evaluated a bit further we might want to provide
something like the attached patch in an update...
