Hi Ric,
As far as I know, VX11 chipset's Chrome 645 graphics is an S3 Graphics design, and contrary to what people may say, it has very little to no design commonality with VIA Technologies Chrome graphics. (i.e., hardware registers)
I have seen some indications that VIA Technologies Chrome9 graphics engine's 3D engine was borrowed from S3 Graphics DeltaChrome graphics (a discrete AGP graphics chip released in 2003 or so), but the 2D and video engines of Chrome9 are mostly register compatible with older UniChrome Pro graphics.
VIA Technologies / S3 Graphics have never released any public documentation to write graphics device drivers for S3 Graphics Chrome graphics, and no open source code has ever been released.
All there is I know for Chrome 645 graphics is a binary blob device driver.
Even if hardware register documentation and / or open source code were available, I will likely start a brand new graphics stack for S3 Graphics Chrome graphics rather than somehow adding hardware support to OpenChrome.
Regards,
Kevin Brace
