This depends on the card. It might be, that it is possible to set up the Z
buffer at a late time. However it might as well be, that it must be done at
mode setup time (or the mode must be re-setup). An example would be an
"inlined" Z buffer, that is interleaved with the pixel data. 

So basically I'd say it depends on the card. And as long as the LibGGI
driverlib module knows how to access it, it should be irrelevant where it
is implemented.
