You are right, to some degree. Actually I have no strong evidence to
support this either. Since KVM doesn't set MTRR, by hunch I thought
VMware might having similar shortages. Also nothing bad can be
observed after the system booted, so I guessed that warning was
useless. Moreover, none other OSes (include old Linux kernels) is
complaining about this in VMware so users of VMware might think 2.6.27
is buggy on this.

Hope someone from VMware could clear this up. I think they are
working on this problem followed this thread. I'd be happy to help.

Li, Yan
