在内核中加入了drm、i915drm后，问题似乎升级了：
CODE:

# cat SYSKNL
....
device agp
....
device drm
device i915drm
....
编译、安装、重启，发现设备里出了点问题：....
device agp
....
device drm
device i915drm
....

定睛一看，原本好端端的/dev/agpgart居然不翼而飞！无奈间，打开google（顺便BS下别扭的谷歌），看到了FreeBSD列表中一帖，远来这问题不是我自己碰到。这位仁兄说，集成显卡被化妆成AGP卡来用，通过agpgart驱动3D加速。结果agpgart没了drmsub0: <Intel i852GM/i855GM GMCH> port 0x1800-0x1807 mem 0xe0000000-0xe7ffffff,0xd0000000-0xd007ffff irq 11 at device 2.0 on pci0

，真是让人哭笑不得。CODE:
[Copy to clipboard]
# dmesg | grep agp
# ...别看了，没agp了
X自然也是这么讲了。# ...别看了，没agp了
