I have this snippet in my /etc/hotplug/usb script to mount my USB disk
when I insert it:
if [ "$PRODUCT" = "58f/9380/100" ]; then
find /dev/scsi -name disc | while read a ; do
/sbin/blockdev --rereadpt $a
done
if sudo -u smurf mount /mnt/key ; then
echo "#!/bin/sh" > $REMOVER
echo "umount -f /mnt/key" >> $REMOVER
chmod +x $REMOVER
fi
fi
This works splendidly with 2.4, but 2.6.0.test4 (where it's arguably
unnecessary...) dies with this message:

This doesn't look like it's PPC specific. I can probably reproduce on
i386 if that would be helpful to anybody.

It is better to decide between our enemies than our friends; for one of our
friends will most likely become our enemy; but on the other hand, one of your
enemies will probably become your friend.
