Paul, this is good to read, but irrelevant.  I'm currently using 2G of
RAM in this machine (less in the others), run several server apps as
well as client apps and 2G of RAM suffices quite nicely.  Only token
amounts of swap are used.  I could upgrade this box to 4G of RAM, but
what for?  It's not needed.  Nothing would run any faster or better.  So
what's the point?

Really...? "blame"...?  If this CPU functions just fine on RH/CentOS 5.6
and other distributions, by what rationale can it be blamed for anything?

Of course I *could* possibly do this.  To what end?  As said, the apps
I'm using wouldn't run any better or faster.  It's much easier and
simpler and faster and cheaper to download a different distribution.

Re: the question.  I wouldn't think so either.  It wouldn't make sense
to require pae for 6.0 but not for 6.1 and beyond.

That "spare time" factor... yeah.  Upgrading CPUs doesn't fit into the
precious few spare time slots in my calendar.

I hope we're not going to start rationalizing the presence of linux bugs
on the basis of Microsoft's record of failures.
