God I hate Linux sometimes.

The problem is not the board... it's the f****n ACPI driver.

Not matter what I do I cannot disable the CONFIG_ACPI_BOOT flag, which controls the ACPI-on-boot function, which in-turn, does the god-awful IRQ allocation seen above. (I assume that it's hard-wired to SMP support or APIC)
The IRQ problem is not BIOS related (The BIOS manual IRQ allocation is being ignored completely). This is a pure Linux problem.
Adding noacpi, acpi=off, acpi=noirq or pci=biosirq does nothing.

Any ideas how can I control the ACPI IRQ routing functions?
Or: how can I force the OS to use the BIOS assigned IRQs?
