cbb0: Could not map register memory

I cannot use my cardbus slots on -current.  My dmesg is:

cbb0: <TI1420 PCI-CardBus Bridge> mem 0x50000000-0x50000fff irq 11 at
device 0.0 on pci2
cbb0: Could not map register memory
device_probe_and_attach: cbb0 attach returned 12
cbb0: <TI1420 PCI-CardBus Bridge> mem 0x51000000-0x51000fff irq 11 at
device 0.1 on pci2
cbb0: Could not map register memory
device_probe_and_attach: cbb0 attach returned 12

I am running with the following in device.hints:
hw.acpi.ec.event_driven="1"
hw.cbb.start_memory="0x20000000"
hw.cbb.debug="1"
hw.cardbus.debug="1"
hw.cardbus.cis_debug="1"
hw.pccard.debug="1"
hw.pccard.cis_debug="1"

I get the same errors whether or not ACPI is enabled.  This is on a IBM
T23, 1 ghz, 384 MB ram.
