不过今天挺幸运，在Gentoo Wiki上看到一篇文章，讲Gensplash，里边讲了如何设置vga。大致的步骤是：
1. 安装lrmi, 里边包含一个vbetest工具；
2. 在终端中运行 vbetest，得到显卡支持的所有vga模式；
3. 在每行开头的中括号里的数字再加上512,就是给kernel传的vga的值了。
我的机器运行vbetest的结果是：

比如我选1680x1050、24位模式，vga就是361+512=873。
后来又看了Wiki上关于VBE的介绍，才知道1680x1050的还没有定义。所以对于这个分辨率的vga代码，不同厂商的定义似乎是不同的，看来还不能像传统4:3的那些代码记住就行了。
不论如何，现在终端里的字体终于不再是矮胖型的了。
