You may try "eject".

eject -s /dev/sda indeed turns the iPod into the "OK to disconnect"
state, but the command itself hangs and does not respond to CTRL-C. I
had to kill the xterm in order to kill eject.
I'm open to suggestions.
Some dmesg output:

These messages happened _after_ you used the eject command?
This looks like SCSI is trying to revalidate the device immediately. It
shouldn't do that -- it should only revalidate on the next open. Or, at
least, that's what I think it used to do....

Good point.
Florin, please look if you have some daemon running, that opens the
device continiously. Something like an automounter or famd, which keeps
the device busy. Just try it again with everything suspicious shut down.
Thanks,
Kay
