Yes. The only evidence is emperical (Randy Dunlap and I sat down with the motherboard one night and tried loads of different combinations and couldn't get any of them to work. He knows the APIC code much better than I and determined that the IRQ line isn't even routed to the controller at all.)
Then there's the Win2000 errata that claimed that it would not work in SMP mode with this controller at all. I do think that VIA eventually came out with a patch for Win2000 that did something like "noapic" on Linux does.
Other than that, sorry, no "official" documentation at all. There was a lot of discussion on the linux-usb mailing lists for a while about this problem a number of months ago if you want to go dig them up.
