In the case of the old Pcmcia package, there was a bunch of options to take care of that, such as "cb_pci_irq". I didn't try yet the old Pcmcia package to check if this option is working, because I would need to recompile a kernel 2.4.X. But, if the old Pcmcia package was able to do it, it's not impossible.

Currently, I managed to narrow down to : ------------------------------------------------- PCI: Using IRQ router PIIX [8086/7110] at 0000:00:07.0 PCI: IRQ fixup querying PCI -> IRQ mapping bus:0, slot:7, pin:3. pin_2_irq idx:9, apic:0, pin:19. PCI->APIC IRQ transform: (B0,I7,P3) -> 19 querying PCI -> IRQ mapping bus:0, slot:8, pin:0. pin_2_irq idx:16, apic:0, pin:16. PCI->APIC IRQ transform: (B0,I8,P0) -> 16 querying PCI -> IRQ mapping bus:0, slot:17, pin:0. pin_2_irq idx:19, apic:0, pin:18. PCI->APIC IRQ transform: (B0,I17,P0) -> 18 querying PCI -> IRQ mapping bus:0, slot:18, pin:0. pin_2_irq idx:20, apic:0, pin:16. PCI->APIC IRQ transform: (B0,I18,P0) -> 16 querying PCI -> IRQ mapping bus:0, slot:19, pin:0. querying PCI -> IRQ mapping bus:1, slot:0, pin:0. pin_2_irq idx:21, apic:0, pin:18.

PCI->APIC IRQ transform: (B2,I5,P0) -> 18 ------------------------------------------------- The Pcmcia bridge is in slot 19.
Thanks a lot !
