That's a nice theory. But when I use CPU intensive programs like gzip on
SPARC and Intel machines I find that I get about the same amount of work done
MHz for MHz on Intel and SPARC.
In my tests a P2 @ 400MHz is faster than a SPARC at 250MHz.
BTW I don't really care what programs like SPEC-CPU say about CPU
performance. Programs that I run and which use lots of CPU time such as
gzip, and clfmerge run faster on Intel.

What do you mean "lag refresh"? Each pixel suddenly has it's value set to
black.
I did install a new X server (ver 4.0) at the same time. But the problem
also occurs in console mode with no X server running.
