$ sudo ln -s "/usr/src/linux-headers-`uname -r`" /usr/src/linux

Driver openchrome:

svn co http://svn.openchrome.org/svn/trunk openchrome
$ cd openchrome
$ ./autogen.sh --prefix=/usr
$ make
$ sudo checkinstall -D #atualmente (06/09/2008): xserver-xorg-video-openchrome_1:0.2.903-1_amd64.deb
$ sudo dpkg -i xserver-xorg-video-openchrome_1:0.2.903-1_amd64.deb

Instalar os módulos do kernel mesa drm:

cd ~
$ git-clone git://anongit.freedesktop.org/git/mesa/drm
$ cd drm
$ ./autogen.sh --prefix=/usr
$ make
$ sudo checkinstall -D #atualmente (06/09/2008): libdrm_2.4.0-1_amd64.deb
$ dpkg -i --force-all libdrm_2.4.0-1_amd64.deb
$ cd linux-core
$ make LINUXDIR=/lib/modules/`uname -r`/build DRM_MODULES=via
$ sudo cp *.ko /lib/modules/`uname -r`/kernel/drivers/char/drm/
$ sudo depmod -ae
