It complies somewhat with the corresponding VESA function

Arguments:
adaptnum: 0=CRT1(analog), 1=CRT2/LCD(digital), 2=CRT2/VGA2(analog)
CRT2 DDC is only supported on SiS301, 301B, 301C, 302B.
LCDA is CRT1, but DDC is read from CRT2 port.
DDCdatatype: 0=Probe, 1=EDID, 2=EDID+VDIF, 3=EDID V2 (P&D), 4=EDID V2 (FPDI-2)
buffer: ptr to 256 data bytes which will be filled with read data.
