ia64 (aka Itanium) is a different architecture than amd64 (also called x86-64).
Exactly. The architectures ia32 (aka x86) and amd64 (aka x86-64, plus many other names) are closely related to each other and both are primary architectures for HelenOS.
The ia64 architecture, on the other hand, is mostly unrelated to ia32 and amd64 (*). HelenOS works on ia64 (despite the fact that the support is not so shiny and there are many features still missing). You can either use the ski [1] emulator (this is what tools/ew.py runs) or a real machine based on the Intel 440GX chipset (I believe that Simics still provides some limited emulation of such a machine, but gaining access to Simics is rather complicated nowadays).
