Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

9603 Since this is probably called before the mode is changed,
9604 we use our pre-detected pSiS-values instead of SiS_Pr as

9607 Arguments:

9609 CRT2 DDC is only supported on SiS301, 301B, 301C, 302B.
9610 LCDA is CRT1, but DDC is read from CRT2 port.

9612 buffer: ptr to 256 data bytes which will be filled with read data.
9613
9614 Returns 0xFFFF if error, otherwise
