It introduce a workaround for one hardware bug, and it support now
more AMD processors.  So yes, this should fix hangs if powerd
is activated.

Note that people reported another problems but with acpi_throttle,
which happens to be a complete different problem.
my best guess for now is that the lapic timer is stopped when
the processor is throttled, and desactivating apic will
help to see if that guess is correct.
