This code makes no sense to me.  exaGetPixmapFirstPixel() returns a pixel
value.  Interpreting that as a pointer to the first pixel must be wrong.

Note that the actual usage of mgaDownloadFromScreen() is #if 0'ed out. 
Perhaps this code should just be removed from the driver?  Or perhaps the
code was #if 0'ed out because the code didn't work?
