9604 Since this is probably called before the mode is changed,
9605 we use our pre-detected pSiS-values instead of SiS_Pr as

9607
9608 Arguments:
9609 adaptnum: 0=CRT1(analog), 1=CRT2/LCD(digital), 2=CRT2/VGA2(analog)
9610 CRT2 DDC is only supported on SiS301, 301B, 301C, 302B.
9611 LCDA is CRT1, but DDC is read from CRT2 port.
9612 DDCdatatype: 0=Probe, 1=EDID, 2=EDID+VDIF, 3=EDID V2 (P&D), 4=EDID V2 (FPDI-2)
9613 buffer: ptr to 256 data bytes which will be filled with read data.
9614
9615 Returns 0xFFFF if error, otherwise
9616 if DDCdatatype > 0: Returns 0 if reading OK (included a correct checksum)
