Help needed with IRQ on Ali chipset

Hi!

I am asking once more for help with IRQ setup for Cardbus controller on
ATI U1/Ali 1535+ chipset. This time with more exact information. This is
what I get:

lspci -v -s 00:0a.0
00:0a.0 CardBus bridge: O2 Micro, Inc.: Unknown device 6972
        Subsystem: Hewlett-Packard Company: Unknown device 0024
        Flags: bus master, slow devsel, latency 32, IRQ 5
        Memory at 80000000 (32-bit, non-prefetchable) [size=4K]
        Bus: primary=00, secondary=02, subordinate=05, sec-latency=32
        Memory window 0: 81000000-81100000
        I/O window 0: 00003000-0000307f
        I/O window 1: 00000000-00000003
        16-bit legacy interface ports at 0001

Which is consistent with Windows IRQ 5

But dump_pirq gives:
Interrupt routing table found at address 0xfdf10:
  Version 1.0, size 0x00d0
  Interrupt router is device 00:07.0
  PCI exclusive interrupt mask: 0x0000 []
  Compatible router: vendor 0x10b9 device 0x1533
....(skipped)

Device 00:0a.0 (slot 0): CardBus bridge
  INTA: link 0x06, irq mask 0x00a0 [5,7]

Device 00:12.0 (slot 0): Ethernet controller
  INTA: link 0x02, irq mask 0x0880 [7,11]

Device 00:0c.0 (slot 0):
  INTA: link 0x03, irq mask 0x0658 [3,4,6,9,10]

Interrupt router at 00:07.0: AcerLabs Aladdin M1533 PCI-to-ISA bridge
  INT1 (link 1): irq 10
  INT2 (link 2): irq 11
  INT3 (link 3): unrouted
  INT4 (link 4): unrouted
  INT5 (link 5): unrouted
  INT6 (link 6): irq 11
  INT7 (link 7): irq 3
  INT8 (link 8): irq 5
  Serial IRQ: [enabled] [continuous] [frame=21] [pulse=12]

So INT6 instead of 5 gets 11 but it is not shown in lspci.

Could somebody, please, tell me what and where should be fixed
(I guess in pci-irq.c) to get it correct.

BR,

Jacek
