cpu model code (fwd)

[joel at OARcorp.com (joel at OARcorp.com)]

If someone knows of an independently and actively maintained cpuModel
determination routine, it would be nice to know about it.  It would
certainly let someone else keep up with the awful pace of change. :)

This is the email which triggered this chain of thought.

I suspect that there's somebody on the net who maintains a bit of code that 
will identify _any_ x86 version, variant, or clone (in excruciating 
detail).  The van Gilluwe book has such code in it, but of course it gets 
out of date quickly.

Perhaps it would be easiest just to look on likely places like x86.org and 
just use whatever conventions are already available, just as RTEMS includes 
and tracks newlib and now the BSD stack.

Then of course we can argue about how to use the options, whatever they are.
