PCI IRQ problems in pre6-3

I just tried 2.3.99-pre6-pre3 on my vaio n505x.

I received the following on bootup (trimmed for relevance):

PCI: PCI BIOS revision 2.10 entry at 0xfd9be, last bus=0
PCI: Using configuration type 1
PCI: Probing PCI hardware
PCI: Using IRQ router PIIX [8086/122e] at 00:07.0
Limiting direct PCI/PCI transfers.
usb-uhci.c: USB UHCI at I/O 0xfca0, IRQ 9
PIIX4: IDE controller on PCI bus 00 dev 39
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Linux PCMCIA Card Services 3.1.11
  options: [pci] [cardbus] [pm]
Adding cardbus controller 0: Ricoh Co Ltd RL5c475
PCI: No IRQ known for interrupt pin A of device 00:0c.0. Please try using pci=biosirq
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Yenta IRQ list 0000, PCI irq0
3c589_cs: RequestIRQ: Resource in use
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

And was unable to access the network.

So I rebooted with pci=biosirq on the command line and I got:

PCI: PCI BIOS revision 2.10 entry at 0xfd9be, last bus=0
PCI: Probing PCI hardware
PCI: Using IRQ router PIIX [8086/122e] at 00:07.0
Limiting direct PCI/PCI transfers.
usb-uhci.c: USB UHCI at I/O 0xfca0, IRQ 9
PIIX4: IDE controller on PCI bus 00 dev 39
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Linux PCMCIA Card Services 3.1.11
  options: [pci] [cardbus] [pm]
Adding cardbus controller 0: Ricoh Co Ltd RL5c475
PCI: No IRQ known for interrupt pin A of device 00:0c.0. Please try using pci=biosirq.
Yenta IRQ list 0000, PCI irq0
3c589_cs: RequestIRQ: Resource in use

Or, in other words. No change, and still unable to use my pcmcia
network card.

I've dropped back to 2.3.99-pre3 for now.
