PCMCIA IRQ broken by new IRQ router in 2.3.99-pre5

The PCMCIA driver worked fine until kernel 2.3.99-pre3. pre4 crashed on boot,
and pre5 boots and runs just fine except that now PCMCIA can't get an IRQ.
This is on my Sony VAIO PCG-505TR, Mobile Pentium 300, 64M RAM, i82365 chipset.
PCMCIA is compiled into the kernel (not a module). From /var/log/messages:

2.3.35:

2.3.99-pre5 with "pci=biosirq" option:
kernel: Linux PCMCIA Card Services 3.1.11
kernel: options: [pci] [cardbus] [pm]
kernel: Adding cardbus controller 0: Ricoh Co Ltd RL5c475
kernel: PCI: No IRQ known for interrupt pin A of device 00:0a.0.

Suggestions welcome.
