IMHO this is a (quite common) miss-conception. There are millions of 
embedded devices that run Linux without any graphics, (here, the 
hardware does not provide graphics at all, and often not even a 
character based display). With servers there is no need to activate the 
graphic stuff - even if running on a PC that does have graphics 
hardware. So you can free a lot RAM for more useful stuff.

By definition "Linux" is just the Kernel. The graphics hardware of 
course is accessed by a dedicated Kernel-mode driver (usually a loadable 
module), providing a "frame buffer" interface to the userland software. 
AFAIK, the X-Server (if used) is just a user land program, accessed by 
some kind of byte stream (pipe) by the user land programs that want to 
create a GUI.
