I have PCI_BUS_FIXUP on a 5.0_RC1 kernel; I can boot it when I
use userconf to disable firewire (else I get NMI); the cardbus 
bridges complain about wrong VCC request and disable themselves.
As a result, no pcmcia, either.

NetBSD-4 (which works) shows:

cbb0 at pci0 dev 12 function 0: Ricoh 5C478 PCI-CardBus bridge (rev. 0x80)
cbb1 at pci0 dev 12 function 1: Ricoh 5C478 PCI-CardBus bridge (rev. 0x80)

cardslot0 at cbb0 slot 0 flags 0
pcmcia0 at cardslot0
cbb1: interrupting at irq 9
cardslot1 at cbb1 slot 1 flags 0

NetBSD-5RC1 shows

That's a GENERIC with:

options         PCIVERBOSE      # verbose PCI device autoconfig messages
#options        PCI_CONFIG_DUMP # verbosely dump PCI config space
# IDE controller on Toshiba Portege 3000 series (crippled PCI device)
# PCI bus support
# Configure PCI using BIOS information
options         PCIBIOS                 # PCI BIOS support
options         PCIBIOSVERBOSE          # PCI BIOS verbose info
#options        PCIBIOS_IRQS_HINT=0x0a00 # PCI interrupts hint. IRQ 9 or 11
options         PCIBIOS_INTR_GUESS      # see pcibios(4)
#options        PCIINTR_DEBUG           # super-verbose PCI interrupt fixup
# PCI fixups, for both PCIBIOS and ACPI
options         PCI_ADDR_FIXUP          # fixup PCI I/O addresses
options         PCI_BUS_FIXUP           # fixup PCI bus numbering
options         PCI_INTR_FIXUP          # fixup PCI interrupt routing

Hope this helps.
