No problem whatsoever with the Intel PXA255.  The LCD controller is
one of the internal gadgets.  This is an ARM9 and runs Linux - see
www.gumstix.com.

There is a driver built into the kernel and documentation is available
on how to activate it.

It is worth knowing that http://www.nyx.net/%7Ejpurbric/lcd/ has a
schematic for a controller based on the PIC16F877.  However, source is
not offered and there are some glitches according to the author.

I am in the process of building a simple ASCII terminal using this
display (640x480 - monochrome) http://tinyurl.com/lmcoh,  I plan to
use the Atmel ATmega128 because I don't want to be bothered with 3.3V
-> 5V translation.  If it wasn't for that little problem, I would just
use the LPC2106.  In either case, the character generator will be in
flash and the frame buffer will be external - DRAM initially but
probably SRAM later on.

I built this Z80 with CP/M project on an FPGA a couple of years ago. 
Now I would like to delete the VGA output and use the LCD ASCII
terminal with TeleVideo TV950 emulation.  Eventually, I would like to
port the LCD controller to the FPGA but I am short of pins.  Hm...
