Dear Xavier and all, 

Here is a register update for VX855(Chrome9 HCM) and VX900(Chrome9 HD)
that should change in function VIAMapMMIO().
========= * current
/* Unlock CRTC. */
ViaCrtcMask(hwp, 0x47, 0x00, 0x01);

The CRTC protect bit in 3X5.47 of VX855 and VX900 are redefined to be
3X5.47[4] instead of 3X5.47[1].
Please help update it specifically for VX855 and VX900.

Thanks you all.
