Diebold voting machines using DES? DES was cracked in 1997

I'm hearing reports that the Diebold voting machines apparently used the Data Encryption Standard (DES). The reason this matters is DES was cracked in 1997 and it was publicly demonstrated how to crack it in 1999. Do you know anyone who can look at the source code? If these reports are true then NO ELECTION THAT USED Diebold equipment should be considered valid.
