Reviewed / Revised earlier version;
Added -march= options vs known cores table for gcc-2.95.3 through 4.5.dev.
File at above link updated.

Yuck.  I wonder why nobody tackled this mess before now? ;)

Not too surprising, not only are most of these machines being shipped with
an Aug. 2005 kernel, a compiler is being used that is too old to provide
code generation support specific to the core being used.  Double yuck.
