    If you have the socket driver as a module, as some (most?) distros do,
    then of course such cards won't be detected at boot time.  If PCMCIA
    and the socket driver are built-in, along with the card driver, then
    I guess this possibility may well exist - it does for NE2K cards.
    
    Since I don't use CF cards with PCMCIA here, I can't say what the ide-cs
    behaviour actually is.  This is why I'm trying to encourage folk to
    explore the kernels new behaviour.
