Well, this is based in tests along this 4 years, with my two computers. Like Bjorn said, we don't have any specification of VIA chipsets. But I like to try, use this quirks only if system don't have IO-APICs enabled. Many VIA systems work like that, for example my old laptop. For me, I know that my old laptop needs the quirks and run with interrupts in XT-PIC, and with my new desktop, I quit sure that don't need the quirks and system runs with interrupts in IO-APIC-edge and IO-APIC-level. Based in, what I read in this original thread http://lkml.org/lkml/2005/8/18/92 , seems to me, that we could try this solution, if we have a easy way to know what kind of interrupts have the device.
