9217 Since this is probably called before the mode is changed,

9221 Arguments:

9223 CRT2 DDC is only supported on SiS301, 301B, 301C, 302B.
9224 LCDA is CRT1, but DDC is read from CRT2 port.
9225 DDCdatatype: 0=Probe, 1=EDID, 2=EDID+VDIF, 3=EDID V2 (P&D), 4=EDID V2 (FPDI-2)
9226 buffer: ptr to 256 data bytes which will be filled with read data.
9227
9228 Returns 0xFFFF if error, otherwise
9229 if DDCdatatype > 0: Returns 0 if reading OK (included a correct checksum)
