Verified that this is the case on my VS3100/M38 as well.  I'll test it on
the M30 after I get some sleep.  I was consistently getting 7142 dhry/s
with the new kernel, which is approaching twice as meaninglessly as fast
as before.  Amazing what that little 1K of cache can do.

Well, I think a nearly 2X performance increase will keep me quiet on the
cache subject for a while.  I'm just glad this went from discussion to
implementation in less than a week.
