I'm also thinking about a possible future extension to triple or quad LVDS. As I'm not aware of English word equivalents of even/odd for triple/quad, perhaps this should be specified using a numerical value instead? If I go too far, please just say so ;-) Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@xxxxxxxxxxxxxx In personal conversations with technical people, I call myself a hacker.
