these screens are integrated into a lot of the hardware i'm dealing  
with lately, my pdev machine has a very old but truly great blue  
160x64 from .. ermm .. some german ripoff of crystalfonts, i suppose.   
a nice way to keep sysload and other stats on the screen while you  
push the machine around doing other things.  run swar, and so on.

treat it like a printf() and "tee /dev/ttyLCD0" while you're hacking,  
and you're good to go, bonus points if you exploit the onboard  
terminal capabilities (shift region, 'pages', charset re-code, etc.)  
and if you shop around you can get one that will just do graphics and  
text through a hazeltine or vt10x termcap, even ..

be aware that many have a small 8-bit microcontroller onboard that can  
confuse you if you do not turn it off/exploit its 'features'.
