Add another machine is not that difficult, as Yocto is designed to be 
highly customizable for different H/W. What you need is a BSP layer for 
your H/W, it is basically the H/W specific configuration, e.g. the 
kernel config, graphics config.

the BSP Guide 
(http://www.yoctoproject.org/docs/bsp-guide/bsp-guide.html) has good 
info on how to write BSP. Also you can find some example from existing 
BSP, like meta-intel BSP 
(http://git.pokylinux.org/cgit/cgit.cgi/meta-intel/)
