9400
9401 Since this is probably called before the mode is changed,
9402 we use our pre-detected pSiS-values instead of SiS_Pr as
9403 regards chipset and video bridge type.
9404
9405 Arguments:
9406 adaptnum: 0=CRT1(analog), 1=CRT2/LCD(digital), 2=CRT2/VGA2(analog)
9407 CRT2 DDC is only supported on SiS301, 301B, 301C, 302B.
9408 LCDA is CRT1, but DDC is read from CRT2 port.
9409 DDCdatatype: 0=Probe, 1=EDID, 2=EDID+VDIF, 3=EDID V2 (P&D), 4=EDID V2 (FPDI-2)
9410 buffer: ptr to 256 data bytes which will be filled with read data.
9411
9412 Returns 0xFFFF if error, otherwise
9413 if DDCdatatype > 0: Returns 0 if reading OK (included a correct checksum)
9414 if DDCdatatype = 0: Returns supported DDC modes
