Not at all. dom0 appears to be 100% ok whatsoever.

In theory yes but in reality I am not convinced. Note that I was able to 
load even FreeSBD kernel but my NetBSD want to run on the other desktop 
HW only???

Ok lets' put it that way. It's not the cciss driver then (which 
eventually crashed my NetBSD dom0 hence gone for SuSE Linux dom0) it is 
something else about my Proliant DL380. The HW doesn't seem to be 
transparent enough and yes changing HW makes difference (note: both dom0 
appears to be 100% and I was unable to diagnose any error, or problem 
about them) otherwise I wouldn't have been able to load the same config 
on the same OS on another desktop HW.
