>Description:
	NetBSD fails to probe the CardBus controllers in IBM T41p and
	IBM T40p laptops.

	On the T41p, the CardBus controller is shown as

vendor 0x104c product 0xac46 (CardBus bridge, revision 0x01) at pci2 dev 0 function 0 not configured
vendor 0x104c product 0xac46 (CardBus bridge, revision 0x01) at pci2 dev 0 function 1 not configured

	and later as

pcic0 at isa0 port 0x3e0-0x3e1 iomem 0xd0000-0xdffff irq 
pcic0: controller 0 (Intel 82365SL-DF) has sockets A and B
pcmcia0 at pcic0 controller 0 socket 0
pcmcia1 at pcic0 controller 0 socket 1
isapnp0: no ISA Plug 'n Play devices found
pcic0: controller 0 detecting irqs with mask 0xde18: none
pcic0: no available irq; polling for socket events

	whereas on the T40p, the CardBus controller is shown as

vendor 0x104c product 0xac55 (CardBus bridge, revision 0x01) at pci2 dev 0 function 0 not configured
vendor 0x104c product 0xac55 (CardBus bridge, revision 0x01) at pci2 dev 0 function 1 not configured

	and later as

pcic0 at isa0 port 0x3e0-0x3e1 iomem 0xd0000-0xdffff irq 
pcic0: controller 0 (Intel 82365SL-DF) has sockets A and B
pcmcia0 at pcic0 controller 0 socket 0
pcmcia1 at pcic0 controller 0 socket 1
isapnp0: no ISA Plug 'n Play devices found
pcic0: controller 0 detecting irqs with mask 0xde18:..3..4..9..10
pcic0: using irq 3 for socket events

	However, insertion of a Lucent wi(4) card does not produce any
	response.

	The complete boot messages from these two laptops follow:

>How-To-Repeat:
	Boot either an IBM T41p or IBM T40p and watch the CardBus
	controllers not being recognized.

	Try to insert a pcmcia card, and watch it not being probed.

>Fix:
	Sorry, don't know exactly.

	0xac46 = PCI4520YENTA
	0xac55 = PCI1520

	according to our pcidevs, both manufactured by TI, but neither
	has any explicit support in sys/dev/pci/pccbb.c, array
	yc_chipsets[], so are not probed/recognized.

	Looking at FreeBSD's sys/dev/pccbb/pccbb.c, it would seem that
	the PCI1520 could easily be supported by just adding an entry
	entry to the above mentioned array, and it's an open question
	whether the same would be true for the 4520 (FreeBSD has 4510
	supported in the same way, whereas we don't).
