So using 7113 would mean, that the PIIX4 stuff gets mixed with PIIX3

It's irrelevant to any OS that i know of.
;-)
Beside that, a PIIX3-ACPI-device doesn't seem to exist in the
pciid-database.
Huh?
# cat /usr/share/misc/pci.ids|grep -i PIIX3
7000 82371SB PIIX3 ISA [Natoma/Triton II]
7010 82371SB PIIX3 IDE [Natoma/Triton II]
7020 82371SB PIIX3 USB [Natoma/Triton II]
# cat /usr/share/misc/pci.ids|grep -i PIIX4
7110 82371AB/EB/MB PIIX4 ISA
7111 82371AB/EB/MB PIIX4 IDE
7112 82371AB/EB/MB PIIX4 USB
7113 82371AB/EB/MB PIIX4 ACPI
See? No PIIX3 ACPI device. That's all i tried to say.
Ok.
More to the point, no machines i have in my vicinity has a PCI device
dedicated to the ACPI. QEMU(old chipsets?) needed it to simplify
delivery of SCI (which must support sharing and be level sensetive)
having PCI device simplifies this somewhat (even though i believe QEMU
does it wrong currently)
There is zero functionality in 7113 or whatnot, it is/was simply a
convenience feature.
