Great improvement in laptop with different acpi boot options

Hi,

As requested I'm sending this mail to notify that the behavior of my laptop (Sony VAIO VGN-FZ21S) improves when I add the following to options to my kernel:

acpi_apic_instance=2
acpi_osi=Linux

Before this change:

1) The fans were always running full speed
2) The temperature measures were higher
3) In my core cpu, it seemed that both cpus were not independent of each other, but always with same load.

Now all these erratic behaviors have been fixed.

Best regards.
