[vine-users:064779] cannot libretto100 800x480

[Michio Ruby <michio@xxxxxxxxxxxxxx>]

 小川です。実は困っています。
libretto100 にVine2.0CRを入れて、いじっているのですが、
Xが800x600でしか使えません。色々MLなどで見てみましたが、1999年に1件
（libretto100の記事）あるだけでした。インストール後何もしなくて
もXは800x600で立ち上がったのですが、800x480で画面の下を表示させたくて、
XF86Setupで/etc/X11/XF86Configをつくりました。しかし、viで編集して
800x480に書き換えると、Xが立ち上がらなくなります。
(--)SVGA:There is not mode definition named "800x480"
とのメッセージがでます。

以下にXF86Configを書きます。少し長いですが、どなたかよろしくお願いします。
