[clug] Disconnecting USB drives cleanly

When a usb drive is plugged in; a kernel driver grabs it
 and presents it to the system as scsi device  /dev/sda1

With the appropriate line in /etc/fstab
/dev/sda1       /media/thumb    auto    rw,noauto,user,sync     0 0
 any user can say "mount /media/thumb" and use it.

Ejecting it with "umount /media/thumb"
 should get it synced and safe to unplug.

But back at the kernel level there is great consternation
 about a scsi drive going missing.
Fills /var/log/messages with alarming warnings.

Any way to tell the driver to let go gracefully?
Especially if it would put the flashing light out
 so you could see when it was safe to unplug it.
