把系统升级到ubuntu 8.04 后分辨率变为800*600, Google找到开源的OpenChrome驱动支持P4M890, 就自己手动编译:

border@b0rder:~$ wget http://openchrome.org/releases/xf86-video-openchrome-0.2.902.tar.gz
border@b0rder:~$ tar xvzf xf86-video-openchrome-0.2.902.tar.gz
sudo apt-get build-dep xserver-xorg-driver-via
cd xf86-video-openchrome-0.2.902/
./configure --prefix=/usr
make
sudo make install
border@b0rder:~$ sudo displayconfig-gtk
通过displayconfig-gtk 选择openchrome驱动就可以
