I don't know if this is helpful at all, but I was able to narrow down the cause
of the bug on my computer to a few D3D formats.

If I change the original line of code:
if (!GL_SUPPORT(gl_formats_template[i].extension)) continue;

to:
if (!GL_SUPPORT(gl_formats_template[i].extension) && (
    gl_formats_template[i].fmt == WINED3DFMT_D16_LOCKABLE || 
    gl_formats_template[i].fmt == WINED3DFMT_D24S8 || 
    gl_formats_template[i].fmt == WINED3DFMT_D24X8 || 
    gl_formats_template[i].fmt == WINED3DFMT_D16_UNORM))
  continue;

the game still does not start.

However, if I change the line e.g. to:
if (!GL_SUPPORT(gl_formats_template[i].extension) && gl_formats_template[i].fmt
!= WINED3DFMT_D16_LOCKABLE) continue;

the game runs fine again. Instead of WINED3DFMT_D16_LOCKABLE, I can also use
WINED3DFMT_D24S8, WINED3DFMT_D24X8, or WINED3DFMT_D16_UNORM.

So the function init_format_texture_info seems to provide wrong data, in my
case at least for the D3D formats WINED3DFMT_D16_LOCKABLE, WINED3DFMT_D24S8,
WINED3DFMT_D24X8, and WINED3DFMT_D16_UNORM, if executes "continue" for these
formats.
