bcwipe claims to be able to wipe block devices.

Even without it, you could make a tomsrtbt disk that starts up and runs
dd over and over on the drive until the macnine is turned off.

while sleep 1 ; do for i in zero urandom ; do dd if=/dev/$i of=/dev/hda ;
done ; done

has always been my favorite. You get a nice quick layer of zeroes in
there every other pass.
