关于内存的使用率，我可以提供我的参考。我在一个64M SDRAM的板子上，用 
nfsroot的方式启动， 运行一个基于X11/gtk+/fontconfig/simsun.ttf的mp3播放 
器(未使用 matchbox)的时候，内存消耗大概是30－40M。 对于一个有128M Nand 
的手持设备来说，采用yaffs+cramfs/Squashfs的解决方案是可以容纳下一个6－ 
8Mbyte的ttf字体的－－－至少我是这么做的。 采用simsun.ttf的最大问题是版权 
问题，不过可以用ttf-firefly-sung （http: 
//cle.linux.org.tw/fonts/FireFly/ ), 这个的版权是"Arphic Public License" 
。 如果你还是担心内存不够，那么你可以考虑使用Compressed caching －－－ 
http://linuxcompressed.sourceforge.net/ , 相当于变相地添加一个"swap".

对于debian官方的fontconfig来说，没有打firefly补丁，这样在显示小字体汉字 
体的时候效果不怎么样。 maemo最好能使用打了firefly补丁的 fontconfig

我个人认为，中文汉字的手写输入还是用商业的手写输入软件比较能保证质量。
