There was a Linux kernel patch which someone claimed made the CardBus on
his Libretto L1 work for him; all it did was force the interrupt to 6.
I did the same in dev/pci/pccbb.c (diff appended to this message) and
it appears to configure now:

cbb0 at pci0 dev 18 function 0: Toshiba ToPIC100 CardBus-PCI Bridge (rev. 0x32) (chipflags 2)
cbb0: socket base address 0x7001000
cbb0: Forcing interrupt to 6.
cbb0: intrpin A, intrtag 6
...
CardBus latency timer 0x20 (10100)
PCI latency timer 0x40 (824000)
pccbb_power: CARDBUS_VCC_0V and CARDBUS_VPP_0V [44]
cbb0: bad Vcc request. sock_ctrl 0xffffff88, sock_status 0xffffffff
pccbb_power: CARDBUS_VCC_0V and CARDBUS_VPP_0V [44]
cbb0: interrupting at irq 6
cardslot0 at cbb0 slot 0 flags 0
cardslot0 attaching CardBus bus...
cardbus0 at cardslot0: bus 1 device 0 cacheline 0x0, lattimer 0x0
cardslotattach: found cardbus on cardslot0
cardbusmatch: busname differs pcmcia <=> cardbus
pcmcia0 at cardslot0
cardslotattach: found 16-bit pcmcia bus
pccbb_pcmcia_card_detect
pccbbattach: found cardslot

But it doesn't detect a card when I've inserted one, or even if I boot
with one in. (I'm not really sure what's supposed to happen on insertion,
if anything, as I've never used CardBus under NetBSD before.)

Thoughts, anyone?
