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

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