Mike,
I see NX in the cpuFlags list: ...syscall,nx,lm,... is that you are reffering to?

Though I think it boils down to the fact that what I'm running it on is a Pentium D, which is the NetBurst architecture. NetBurst is below Conroe, so it would fail to meet the cluster compatibility level of Conroe.
