No, it doesn't.  :-(

Like in the previous try, the slot becomes deaf once I eject the
16-bit PC Card.  Here's the relevant console log:

Injecting cardbus:

: Status is 0x30000920
: cbb0: card inserted: event=0x00000006, state=30000920
: cbb0: cbb_power: 3V
: rl0: <Edimax EP-4103DL CardBus> port 0x1000-0x10ff mem 0xd8000-0xd81ff irq 11 at device 0.0 on cardbus0

: rl0: Ethernet address: 00:11:6b:50:03:82

Ejecting cardbus:

: Status is 0x30000186
: rlphy0: detached
: miibus0: detached
: rl0: detached
: cbb0: cbb_power: 0V

Injecting pccard:

: Status is 0x30000510
: cbb0: card inserted: event=0x00000000, state=30000510
: cbb_pcic_socket_enable:
: cbb0: cbb_power: 5V
: cbb_pcic_socket_enable:
: wi0: <Lucent Technologies WaveLAN/IEEE> at port 0x100-0x13f irq 11 function 0 config 1 on pccard0
: wi0: using Lucent Technologies, WaveLAN/IEEE
: wi0: Lucent Firmware: Station (6.6.1)
: wi0: Ethernet address: 00:02:2d:09:40:19

Ejecting pccard:

: Status is 0x30000116
: wi0: detached
: cbb_pcic_socket_disable

Note there's no "0V" indication now.  At this point, the slot becomes deaf.
