Hi,
Some of yours hardware have same IDs than mine 

you have as relevant ;
cat /usr/include/linux/pci_ids.h  |  grep 3189
#define PCI_DEVICE_ID_VIA_8377_0        0x3189
#define PCI_DEVICE_ID_VIA_82C586_1      0x0571
#define PCI_DEVICE_ID_VIA_82C586_2      0x3038
#define PCI_DEVICE_ID_VIA_8237          0x3227
#define PCI_DEVICE_ID_NVIDIA_GEFORCE4_TI_4800_8X    0x0281

I have 
PCI_DEVICE_ID_VIA_82C586_1 
PCI_DEVICE_ID_VIA_82C586_2
PCI_DEVICE_ID_VIA_8237_SATA 

On kernel 2.6.16.17 enter this patch which, if you don't use kernel-rc
version doesn't change nothing :D
http://www.kernel.org/diff/diffview.cgi?file=%2Fpub%2Flinux%2Fkernel%
2Fv2.6%2Fincr%2Fpatch-2.6.16.16-17.bz2;z=12

if you compile your kernel, you could try remove this 2 lines, 
DECLARE_PCI_FIXUP_ENABLE(PCI_VENDOR_ID_VIA, PCI_DEVICE_ID_VIA_82C586_1,
quirk_via_irq); 
DECLARE_PCI_FIXUP_ENABLE(PCI_VENDOR_ID_VIA, PCI_DEVICE_ID_VIA_82C586_2,
quirk_via_irq); 
to see if ACPI IRQ routing works better: 

Well, this can be done like this 
cd drives/pci
edit and delete the lines on quirks.c
cd ../..
make bzImage
(backup mv /boot/vmlinuz-2.6.16.18 /boot/vmlinuz-2.6.16.18.orig)
mv arch/x86_64/boot/bzImage /boot/vmlinuz-2.6.16.18)
and reboot 

My question which is not meaningfully, because I made a little
confusion, but is if you has used other version of kernel before ?  

Maybe the best is open o bug in bugzilla with a complete dmesg and one
lspci -n , etc.

I am little curious, why your interrupts are XT-PIC and not IO-APIC

Thanks for the report ,
