We're moving ahead with that - there will be a beta version posted on macgamefiles.com sometime today. It won't work on battle.net since it hasn't gone through the full signing/test process for battle.net yet. But it should work correctly on X3100 in both OpenGL and software rendered mode.
Here is the README from the beta.

README for "Diablo II BETA-for-X3100 (Carbon)"
This is a beta release of Diablo II (Carbon) for Mac OS X, which should run correctly on machines with the Intel 965 / GMX 3100 chipset, under all versions of Leopard OS.
As you may know, support for 256-color display mode was removed from the X3100 drivers in mid 2008 and this made Diablo II incompatible. This beta has new code which addresses that conflict.
If you have a machine that is currently running Diablo II correctly, this build will have no additional value for you, and you should continue using your existing copy as-is.
Since this release is a beta edition and has not been made into a finalized patch, please note these issues and limitations.
a) do not replace your existing Diablo II (Carbon) with this application. Just drop this BETA application as-is into your Diablo II folder and run it instead of the original. You will need the original still in place when the patch ships.
b) the BETA version should be able to support single player mode, but due to its beta form will not sign on to battle.net, or be able to patch itself. LAN play has not been fully tested and may work correctly for you, but may have bugs - please keep in mind that this is beta software and we would appreciate any feedback that you have.
c) when the next Diablo II patch is released, you can delete the BETA version, then run the original version and it will be patched.
