It's as if the card was not removed, it seems.

Perhaps a red herring, but as I mentioned, I'm not using ACPI[1].  For a
minute I thought the problem was related to not having the apm module
loaded -- because when I first posted apm was not loaded and card
ejects were not generating events.  And just a minute ago apm was
loaded and card eject events where happening.

But after trying a few times it seems unrelated to having apm loaded
or not.  Seems a bit random.  Debugging is a bit slow, having to
reboot each time.  So I don't have a huge sample size.

Well, I did a rmmod prism54 once today and rmmod hung -- rmmod was
eathing 95% CPU and I couldn't kill -9 it.  Clearly getting in a
confused state.

[1] The reason I'm not using ACPI is because my wireless card doesn't
seem to work with acpi.  With acpi enabled I get this when trying to
run the card:

    ACPI: PCI interrupt 0000:06:00.0[A]: no GSI
    eth1 could not install IRQ handler
    prism54: probe of 0000:06:00.0 failed with -5

BTW -- I did flash the laptop's bios today, just to make sure it was
up to date.  Just in case.
