Would you enumerate these or else explain how we can gather
this information ourselves?  Is it just a matter of reading
driver code or looking in specific configuration files in the
pcmcia-cs package?

It seems like we should both:

1.  Not OOPS when cards are ejected without warning

2.  Have a cardmgr equivalent that schedules a device removal,
    triggering notices to a user to (for example) unmount 
    partitions before removing a cardbus card.  

It seems like there has been general agreement that a cardmgr
replacement is needed, but (IIRC) the replacement hasn't been
well-defined.  Can we start nailing this down, so we can begin
work on building it?
