CDROM problems in fc3 (was Re: What I hope is not in FC3

[Kim Lux]

My CDROM will mount fine, but it never umount and/or eject properly.
The unmounting and ejecting been a problem since FC3rc3 for me.  I used
to be able to umount it with 'umount -l /dev/hdc' or 'umount -
f /dev/hdc'.  Tonight however, I am using grip and the only way to eject
is to reboot.
