Yes, I found it in arch/ppc/kernel/pci.c, function pcibios_fixup_cardbus.
I believe it should be safe to remove that "fixup" once my patch is applied. There is no reason to believe that BIOS or OpenFirmware know better than the Linux kernel how to route interrupts on PCMCIA bridges.
I believe that relying on proprietary firmware (i.e BIOS) or on power-on defaults is only justified when we have insufficient information how to initialize the chip. That's not the case for TI bridges.
By the way, I'll appreciate if somebody applies my patch, removes the PPC fixup and tests it on PPC. I'm 99% sure that it will work, but still it will be good to know for sure.
