That's great. So the final workaround (works in scummvm port) is like this:

#include <SDL/SDL_syswm.h>

void SDL_X11_SetNetWMWindowTypeNormal(){
     SDL_SysWMinfo wminfo;
     SDL_VERSION(&wminfo.version);
     if (SDL_GetWMInfo(&wminfo)){
         Atom atoms[1] = { None };
         Atom net_wm_window_type;

         net_wm_window_type = XInternAtom (wminfo.info.x11.display,
                                           "_NET_WM_WINDOW_TYPE", False);

         atoms[0] = XInternAtom (wminfo.info.x11.display,
                                 "_NET_WM_WINDOW_TYPE_NORMAL",
                                 False);

         XChangeProperty ( wminfo.info.x11.display,
                           wminfo.info.x11.wmwindow,
                          net_wm_window_type,
                          XA_ATOM, 32, PropModeReplace,
                          (unsigned char *)atoms, 1);

     }
}


And it can be called after SDL_Init(SDL_INIT_VIDEO) but before 
SDL_SetVideoMode. When called later the icon will not show immediatelly 
but after minimizing/rearranging windows.

This is of course needed only if you want it working in current beta. It 
won't be needed for future versions.

Also you need to add -I /usr/X11R6/include to gcc, SDL_syswm.h needs it.
