Ok.

I dug a bit more inside the code, in dlls/wined3d/device.c, line 440, there is
the slow_mask:

        slow_mask |= -!gl_info->supported[ARB_VERTEX_ARRAY_BGRA]
                & ((1 << WINED3D_FFP_DIFFUSE) | (1 << WINED3D_FFP_SPECULAR));

Which is at true because my system does not support ARB_VERTEX_ARRAY_BGRA. And
this is why the code fallbacks to immediate mode.

Instead, why not converting the color data to RGBA when drawing ? I'll try to
do this tomorrow.
