I had the idea verifying whether pcmciautils are installed. They are:

merkaba:~> apt-show-versions pcmciautils
pcmciautils/sid uptodate 018-1

And I can=B4t get them do or output anything useful when the card is=20
installed:

merkaba:~> lspcmcia=20
merkaba:~> pccardctl=20
pcmciautils 018

invalid or unknown argument
Usage: pccardctl COMMAND
Supported commands are:
        ls
        insert
        eject
        suspend
        resume
        reset
        info
        status
        config
        ident
merkaba:~#234> pccardctl ls
merkaba:~> pccardctl status
merkaba:~> pccardctl info =20
merkaba:~> pccardctl config
merkaba:~> pccardctl ident=20
merkaba:~> pccardctl eject
merkaba:~> pccardctl reset
merkaba:~> pccardctl resume
merkaba:~> pccardctl resume
merkaba:~> pccardctl info
merkaba:~>

Shouldn=B4t at least one of those commands output *anything* even when that=
=20
ExpressCard is not detected properly? I thought it might at least display=20
that there is an empty ExpressCard slot. So is Linux not recognizing the=20
slot at all?

merkaba:~> apt-show-versions udev      =20
udev/sid uptodate 170-1

=2D-=20
