我的显卡是Intel 965，已经从官方网站上看到，已经支持了，模块是i810，安装步骤如下：

1， 下载src.tar.gz，sys.tar.gz，xenocara.tar.gz，解压到 /usr/src ：
# tar -zxvf srs.tar.gz -C /usr/src
# tar -zxvf sys.tar.gz -C /usr/src
# tar -zxvf xenocara.tar.gz -C /usr/src

2. 安装：

# cd /usr/src/xenocara/driver/xf86-video-intel
# rm -f obj
# make -f Makefile.bsd-wrapper cleandir
# mkdir XOBJDIR
# make -f Makefile.bsd-wrapper obj
# make -f Makefile.bsd-wrapper build


安装后从man手册页已经看到了：

# man i810

DESCRIPTION
i810 is an Xorg driver for Intel integrated graphics
chipsets. The driver supports depths 8, 15, 16 and 24.
All visual types are supported in depth 8. For the
i810/i815 other depths support the TrueColor and Direct-
Color visuals. For the i830M and later, only the True-
Color visual is supported for depths greater than 8. The
driver supports hardware accelerated 3D via the Direct
Rendering Infrastructure (DRI), but only in depth 16 for
the i810/i815 and depths 16 and 24 for the 830M and later.

SUPPORTED HARDWARE
i810 supports the i810, i810-DC100, i810e, i815, i830M,
845G, 852GM, 855GM, 865G, 915G, 915GM, 945G, 945GM, 965G,
965Q and 946GZ chipsets.
