On solsparc in order to launch a 64-bit VM , we could use
  -d64, -server -d64
 The same should work on Itanium bits as well
 eventhough the default on Itanium is 64-bit VM)

However if I specify the d64 arguement , the jvm is not started

Itanium bits used : build 1.4.1-internal-bobv_14_mar_2002_03_48
