提供了解决方法，就是使用 Xorg-6.9.0。

于是编译安装 Xorg-6.9.0 成功，但是安装安装提示运行：
# Xorg -configure
时出错：

Fatal server error:
Cannot open log file "/var/log/Xorg.0.log"

Please consult the The X.Org Foundation support
at http://wiki.X.Org
for help.

/var/log 的权限是没有问题的，问题出在 /usr/X11R6/bin/Xorg 上，因为是基于用户的包管理，所以其属主是 Xorg，但 X 需要 root+suid，所以运行时属主变成了 Xorg，当然没有权限写 /var/log/

于是更改 Xorg 属主：
# chown root /usr/X11R6/bin/Xorg
# chmod u+s /usr/X11R6/bin/Xorg

再次运行，得到如下的错误：

(II) LoadModule: "apm"
(II) Loading /usr/X11R6/lib/modules/drivers/apm_drv.so
dlopen: /usr/X11R6/lib/modules/drivers/apm_drv.so: undefined symbol: XvRTPort
(EE) Failed to load /usr/X11R6/lib/modules/drivers/apm_drv.so
(II) UnloadModule: "apm"
(EE) Failed to load module "apm" (loader failed, 7)

使用 X -config /root/xorg.conf.new 则黑屏，键盘无反应，只能关机。

如果仅从上面的提示来提示来看，则会步入误区，因为实际上 apm 模块并没有实质性的影响，它是电源管理的一部分：
Xorg wiki FAQ

正确的做法是，耐心查看由于运行 startx(Xorg -config ~/xorg.conf.new) 而产生的 /var/log/Xorg.0.log，查找其中所有"error","failed"等可能会是一个比较快捷的方式。因为问题很可能是出在芯片组的驱动上。

log 的内容比较多，但是其中可以看到如下几行：

drmOpenDevice: Open failed
[drm] failed to load kernel module "i915"
(II) I810(0): [drm] drmOpen failed
(EE) I810(0): [dri] DRIScreenInit failed. Disabling DRI.
...
Fatal server error:
Caught signal 11. Server aborting


提示找不到内核的 i915 模块，虽然 /lib/modules 中实际上是有这个模块的。因为之前的内核是我直接从主系统拷贝过去的，包括 initrd-$kernel.img 和 /lib/modules/$kernel 以及 /etc/modprobe.conf，所以问题可能就出在这里。

于是重新编译内核。注意在主系统下用 chroot 来进行编译和启动到 LFS 系统下进行编译可能会有差异，我两次都试过，用 md5sum 校验发现不同。建议启动到 LFS 系统进行编译。可能 Xorg 也需要重新编译，移除原来的 /usr/X11R6/bin/Xorg，运行：
# userpack install -a Xorg-6.9.0
即可。

编译内核时，LFS 没有 initrd，所以一些重要模块如 ext3, jbd, scsi 等需要编译到内核中，我写在了这里：
LFS kernel compling

这次启动 X 没有彻底黑屏，键盘还有响应，也可以按 3 键(CTRL+ALT+DEL)重启，但总的来说还是没有成功。有如下报错：
# Xorg -configure

dlopen: /usr/X11R6/lib/modules/drivers/apm_drv.so: undefined symbol: XvRTPort

Xorg detected your mouse at device /dev/mouse.

Fatal server error:

"(WW) I810: No matching Device section for instance (BusID PCI:0:2:1) found"这个错误并没有什么关系，可以看这里：
Xorg wiki FAQ
用 lspci 可以看到这一点：

00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller (rev 04)
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04)
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04)

所以虽然 0:2:1 找不到，但 0:2:0 可以，如果真的找不到，一般会报告"No screen found"的错误。

只能换一种思路。现尝试编辑配置文件，将 i810 换成 vesa 试试：
# vi /etc/X11/xorg.conf

Section"Device"
    Identifier  "Card0"
    Driver      "vesa"
    # Driver        "i810"
    VendorName  "Intel Corporation"
    BoardName   "Mobile 915GM/GMS/910GML Express Graphics Controller"
    BusID       "CI:0:2:0"
EndSection

这时候是可以启动 X 的，但只能以 root 身份运行，并且不能解决宽屏问题(915resolution)。

再尝试通过运行 xorgconfig 来获得一个配置文件(先将原来的文件备份)，将其 Driver 改成 i810，在运行 915resolution 49 1280 768 之后，startx 竟然可以看到正确的长宽比，但之后就基本上没有什么响应了，twm 的窗口无法正常显示，点击鼠标只显示一些绿色的条纹。

我开始估计是窗口管理器的问题，于是接着安装其他的包，直到将 xfce4 安装之后，再进入 startx，这次可以看到正确的显示了，包括上下两个 panel，但是机器却好像越来越慢，点出来的菜单无法再隐藏，直至最后失去响应。

再使用 vesa 模块，基本上可以，但仍然不能以普通用户身份运行 startx。

所以现在是三个问题：
(1) i810 driver 的问题
(2) normal user startx 的问题
(3) vesa 1280x768
