It was like that in kernel 2.6.16 and previous since, I don't know, 2.6.9 or 2.6.13 ....

I believe this quirks is just for VIA system with interrupts in XT-PIC mode (like my old laptop). > > i'd also like to figure out why the quirk is needed/fails when people > are using ACPI for interrupt routing as presumbly that must work as > windows relies on it
