Michael,

The "green" debugs vs "blue" debugs have a latter revision GPU that
takes advantage of a different VRAM configuration than the original
model. This facilitated some cost savings that are always a priority. A
few other changes were incorporated into the latter rev GPU but they are
fairly minimal.

The "green" debugs more closely represent the actual hardware sold to
consumers. Unfortunatly there is no real good story to tell here, it was
driven mainly because the old GPU's were no longer availible.

And before you ask, the Yaroze hardware (and consumer units) have the
same GPU and VRAM as in the "green" debugs.
