The answer is dependent on how old your laptop is.
My old Compaq Presario 2100 did not work with ACPI enable because it
couldn't control the thermal functionality. But my new laptop (macbook
2,1) it works great with acpi and is needed to get some stuff working.

So I suggest you try enable ACPI and see what happens. If you laptop
can't control the thermal functionality it will most likely just turn
of and then you just need to install it again without ACPI and you'll
be fine. The laptop it self has a protection that it turns if off if
it feels it to hot so you won't burn anything.
