Is there any performance degradation when using ACPI as it uses IRQ 9, therefore forcing more devices to share IRQ's thus possibly decreasing performance?

Well, I can't tell for sure... ACPI is supposed to offer better power management and battery usage for laptops, while being more flexible than APM.
The truth is that on my laptop, both work equally well but since ACPI is still less mature than APM, I chose to use ACPI in order to test it and helping in its future development.

I wouldn't mind about IRQ's...
