2.6.11 seemed to work OK. "cardctl eject" does not unmount the device,
and obviously, just pulling the card out doesn't work either.
Unfortunately, it's not realistic for the project to assume that people
will umount first. If I disable udevd, then 'cardctl eject' will call
/etc/pcmcia/ide and the hda device will still be present so the umount
works.
Thanks.
