Are there any BIOS mods or patches for the DFI K6XV3+/66 to release IRQ 2 from ACPI?

The BIOS has an option to disable ACPI but according to MQDIAG (from PCMIDI), IRQ 2 is still not available.

I've tried using ModBin to modify the BIOS but I don't even see the hidden option that I can enable. However, I think it's possible because keropi is using another super socket 7 motherboard with the VIA3 chip and his BIOS does have the option... ?
