Well, no. The patch attached to this bug only blends the vertices before
passing them to the hardware, it doesn't touch things like lighting or texcoord
generation. Implementing it in hardware means generating shaders to replace
fixed function vertex processing based on the various D3D device states, like
e.g. enabled lights, material settings, etc., and then adding vertex blending
support to that. The last part of adding vertex blending to those shaders is
about the same amount of work as the software implementation, but the first
part of building the infrastructure is a lot of work (although Stefan's
patchset already implements most of that).
