My Athlon64 / K8 socket 939 setup needed the following adjustments to fix
memory read/write errors.  Thanks to Rudolf for hinting on which bits I
should check for.  Details:

 - bit 9, mandated by spec to always be set on sodimm or socket 939 dual

 - bit 28, enable 2T timing.  no idea why, but I get memory errors without

 - bit 29, upper chip select.  mandated by spec on socket 939.

My patch also adds missing descriptions, based on the ones from the spec

  how) you may access your data; but nobody's threatening your freedom: we
  still allow you to remove your data and not access it at all."
