Relation between bug "*** DANGER *** unable to remove socket power" and power
state C3/C4.
1.) inserting pcmcia card
2.) initialize the driver (I use the option module for umts.)
3.) the pcmcia card prevents power state C3/C4 (high power consumption!)


4a.) remove the card without "pccardctl eject" (not a nice solution, because
the card is powered) -> everything works fine, also CPU power state C3/C4 can
be used

-- or --

4b.) remove the card with "pccardctl eject" -> "*** DANGER *** unable ...." and
the CPU power state C3/C4 is unuseable, also after physical removing the card.
