1) X3100 IS a DX10 part. Please check your sources. Here. It can't get more official than that. X3100, X3500 and the future X4500 (on the G45 chipset) are all DX10-capable. Problem is, their drivers only let them work on DX9 mode (and not fully, for that matter...) for now.

2) Gigabyte naming convention for Intel chipsets is as follows:
GA - Gigabyte
G35 - indicates the chipset, and sometimes also the socket, in this case the G35 chipset
M - ALWAYS indicates a mATX part
D - indicates that is part of the "Ultra Durable" series
S - has SATA ports (this has become redundant since the mid-478 era; or it's the only symbol I don't know what means)
2~6 - indicates the level of "OC-friendly" features (and sometimes other features as well, like a more advanced IHS or improved sound codec) present on the BIOS
R - indicates the presence of a ICHxR Southbridge

So, though in fact the GA-G35M-DS3R does NOT exist (Gigabyte doesn't have G35 boards yet), and I don't know if it will ever exist, if it does come out, I'm sure it will be a mATX OC-friendly board.

Cheers.
