debian5.0 基本系统+fvwm 显卡驱动没有装上？

新手，抱歉打扰各位。
用aptitude安装zhcon后运行zhcon --utf8 --drv=vga出错
出错信息大体上说找不到framebuffer/VGA/libggi
运行lspci命令后显示信息中似乎显卡驱动没装。
Intel显卡驱动不是默认装上的吗？ 我的显卡是intel GMA 4500.

不好意思，不应该在fvwm终端使用zhcon
但是在控制台输入zhcon --utf8 --drv=vga 或者zhcon --utf8都会黑屏死机？
已经修改了 /etc/grub/menu.lst 在启动项加上splashvga=0x305

启动项加了 vga=xxx 之后内核就开启了 framebuffer console 的，那么可以用 framebuffer 驱动试试：
看 zhcon 的主页上显示它最近的一次更新是在 2006/05/05，竟然还能用也算是奇迹了……

也不行啊。黑屏，死机。
