After some more googling:

- The Sun 3/xx and Sun 3/xxx can have a hardware DES
  encryption/decryption chip. For Sun 3/50 and Sun 3/60, only the chip
  is needed. For the Sun 3/xxx more logic ICs are needed.
- This chip is Zilog Z8068 or Zilog Z9518 or AMD AmZ8068 or AMD Am9510
  Cost was about $50 back then
- A kernel with des support needs to be compiled
- Encryption speed: somewhere between 1.6 and 1.9MByte/sec
- It is highly likely that Sun never sold the DES chip as an option
  (but you can buy one yourself and put it in your box)
- No stories of users having done this and verified it have been found

I am currently trying to get my hands on one or more of these babies :)
