Don't worry about your english, perfectly straight-forward question. V_BIOS refers to video BIOS, which probably means X can't initialize the card. Now, I think a whole lot of these old 1 Mb video cards got dumped from X support when X moved to the 4.x.x series. I had one of them in an old laptop, so I made it by with 3.3.6, which was all that old thing could handle anyway. You can find out for certain from www.xfree86.org
If that's not the case, it may be a xinerama issue, which according to another Moderator here, Acid Kewpie, is just a pain and a great big mess. Its possible to run X between two monitors without xinerama, the mouse will page over but applications can't be dragged accross, or so that's my understanding at least.
