1.  The report about Windows NT is true.  The released version of NT 4.0 
does it automatically, so you take a performance hit.

2.  Cyrix is still working on the problem.  They're trying to create a 
software patch.  Meanwhile, they have said they will replace the CPU of 
anyone who asks with a newer, fixed version.  (They saw what happened to 
Intel, after all.)

3.  There is no evidence that the problem that Microsoft claims to have 
found has any effect on Linux.
