xf86-video-via-1.31.1-r1: via_dri.h from via driver and Mesa-6.3.2 from
x11-base/xorg-server-0.99.2-r1 are not in sync.

Structure VIADRIRec:
See xorg-server: Mesa-6.3.2/src/mesa/drivers/dri/unichrome/via_dri.h and
xf86-video-via: src/via_dri.h

Both struturces differ in "Bool drixinerama;" and "char drixinerama;"
This leads to the error in Mesa-> viaInitDriver: "ERROR!  sizeof(VIADRIRec) does
not match passed size from device driver".



Reproducible: Always

acutally my last post wasn't true. the difference between both structures lies
in the definition of the structure: viaRegion which is for 
- mesa:

typedef struct {
    drm_handle_t handle;
    drmSize size;
    drmAddress map;
} viaRegion, *viaRegionPtr;

and for xf86-video-via:
typedef struct {
    drm_handle_t handle;
    drmSize size;
} viaRegion, *viaRegionPtr;

MesaLib 6.4 from xorg-server-0.99.3 has the file
./src/mesa/drivers/dri/unichrome/server/via_dri.h
which defines 

typedef struct {
    drm_handle_t handle;
    drmSize size;
} viaRegion, *viaRegionPtr;

structures are in sync again.
