Can PCMCIA cards be inserted and removed with the power on?

Technically: yes.
But often the OS requires 'prior warning' to safely remove
hardware :-)

So: hotplug is supported, hot remove is sometimes allowed.

    CardBus sockets must be able to accept and support all 16-bit

    5 volt only PC Card cannot be supported in any system which supplies
    only 3.3 volts. This is true for both CardBus and non-CardBus

    The CardBus interface supports insertion and removal of cards
    while a system is powered-ON (i.e., Dynamic Reconfiguration). The
    socket must be powered-OFF when a card is not present. To the user,
    this appears as though the socket is "hot" during insertion and
    removal events."

I don't have a spec, but that suggests that perhaps when a PCMCIA
is plugged in, the power is not applied right away.
