I believe so - the platform I have is based around the Open Embedded
stuff, and there's a button on the desktop which communicates with the
kernel via the PCMCIA ioctls. One of the things it offers is to allow
media (eg, CF) to be safely ejected without ending up pulling the card
out while the FS is still mounted.
If the button can't communicate with the kernel PCMCIA driver, it doesn't
know that a CF card is in place, so it can't offer to eject the media.
