from xf86.h :

/* xf86DGA.c */

#ifdef XFreeXDGA
extern _X_EXPORT Bool DGAInit(ScreenPtr pScreen, DGAFunctionPtr funcs,  
DGAModePtr modes,
                         int num);
extern _X_EXPORT Bool DGAReInitModes(ScreenPtr pScreen, DGAModePtr  
modes, int num);
extern _X_EXPORT xf86SetDGAModeProc xf86SetDGAMode;
