Undoubtedly :( But it used to work when I used your i82365 module instead of
the kernel's yenta module. The i82365 module now gives the same failure
output as the yenta module.

I modprobed the following to get things up and running, (all your pkg)
pcmcia_core, i82365, and ds. Then ran cardmgr. All was well. Now when I
load i82365, it yields the pci irq failure and the irq type is changed.

2nd sentc: What changed in the last two-three weeks? I notice that the
current pcmcia (yours) code loads a new module called pci_fixup.

The dmesg output from loading i82365 is:

Intel PCIC probe: <4>PCI: No IRQ known for interrupt pin A of device 00:03.0.

PCI: No IRQ known for interrupt pin B of device 00:03.1.

Ricoh RL5C478 rev 03 PCI-to-CardBus at slot 00:03, mem 0x10000000
host opts [0]: [isa irq] [io 3/6/1] [mem 3/6/1] [no pci irq] [lat
168/176] [bus 2/5]
host opts [1]: [serial irq] [io 3/6/1] [mem 3/6/1] [no pci irq] [lat
168/176] [bus 6/9]
ISA irqs (default) = 3,4,7,11 polling interval = 1000 ms

Previous output was:
Ricoh RL5C478 rev 03 PCI-to-CardBus at slot 00:03, mem 0x10000000
host opts [0]: [serial irq] [io 3/6/1] [mem 3/6/1] [no pci irq] [lat
168/176] [bus 2/5]
host opts [1]: [serial irq] [io 3/6/1] [mem 3/6/1] [no pci irq] [lat
168/176] [bus 6/9]
ISA irqs (default) = 3,4,7,11 polling interval = 1000 ms

Notice the change from serial irq to isa irq.
