Thanks for your continued help... this gave me some extremely
interesting data. Here's some data from /proc/interrupts on
2.6.0-test9, which was quite stable for me:
19: 0 0 IO-APIC-level au88xx
21: 52 0 IO-APIC-level uhci_hcd, uhci_hcd

2.6.5 with ACPI:
11: 300000 0 IO-APIC-level uhci_hcd, uhci_hcd
19: 299999 1 IO-APIC-level au8830

2.6.5 with pci=noacpi:
5: 54 1 IO-APIC-level uhci_hcd, uhci_hcd, au8830

I haven't run that third setup for a lot of time yet, so I don't know
for sure that it's stable. Sound seems much more crackly than it was
with ACPI enabled, but that could be any problem with the vortex2
driver - or it could be missing interrupts.

Here's one interesting bit that only appears in dmesg with ACPI
enabled, and only in 2.6.5:

PCI: Via IRQ fixup for 0000:00:07.2, from 5 to 11
PCI: Via IRQ fixup for 0000:00:07.3, from 5 to 11

That's the two UHCI devices. So they get quirked off to a different
IRQ, and au88x0 somehow ends up routed to yet a third IRQ, but from the
symptoms I am guessing that the USB and au8830 are actually connected
to the same pin. That would explain both of them getting interrupts
with no obvious source, even though they do each get their own
interrupts also.

The quirk isn't new; it's from 2002. So presumably ACPI is now putting
them somewhere different than it used to. Here's a some bits of the dmesg:

2.6.0-test9

ACPI: PCI Interrupt Link [LNKA] enabled at IRQ 11

IOAPIC[0]: Set PCI routing entry (2-10 -> 0x79 -> IRQ 10 Mode:1 Active:1)
00:00:07[B] -> 2-10 -> IRQ 10
ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 10
ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 11

I've attached the dmesgs and /proc/interrupts.

In the interest of full disclosure, this motherboard came with a bad
_PRT. There are a four entries in the APIC-mode _PRT which look like:
Package(0x4) {
0x0007ffff,
0x0,
0x0,
\_SB_.PCI0.LNKA,
},

With that, ACPI complains and/or can't boot (don't remember exactly).
So I've fudged them to:
Package(0x4) {
0x0007ffff,
0x0,
\_SB_.PCI0.LNKA,
0x0,
},

I made this change some months before the 2.6.0-test9 kernel which
worked OK.
