I audited our system running under various operating systems.
The following OS do _not_ pad the packets with zero but something else, if
anybody is interested in the dumps of the frames produced while testing, feel
free to contact me.

Machine OS Version

IBM iSeries OS/400
IBM RS/6000 AIX 4.3
Sun E450 Solaris 8
HP Printers JetDirect Various

Identification of the vunerability was done by "ping -s1 <host>" and analysing
the resulting answers using ethereal, looking if the ethernet trailer was
different from all zero.
