I'm not convinced by that site.

DSDTs are part of the BIOS interface to ACPI (Advanced Configuration and
Power Interface). BIOS ACPI implementations are notoriously buggy, and
can easily crash kernels. So you may need to turn that off (noacpi --
you'll lose hardware power-off).

An APIC (Advanced Programmable Interrupt Controller, which is
responsible for interrupt balancing, as you say) is pretty unrelated.
You may well be able to turn off ACPI without turning off APIC.

Hope this helps,

James.
