You may have to use a bare-bones hardware configuration. You'll need at 
least 8.4 Update V0600 to even boot. (Poulson has 128 registers in the 
rotating set instead of the previous 96, which required changes in SWIS 
code to even boot.) Update V0900 is the latest Update ECO kit out so far.

One customer did some in-house testing of OpenVMS on an 8-core i4 Blade 
configuration and reportedly found about a 25% increase in performance, 
even though of course there isn't any optimization in the compilers or 
OS to take advantage of Poulson.

Since HP hasn't done the usual depth of qualification and testing and 
fixing of problems found, it's unsupported, of course.
