What processor are you using? Epson makes good controllers for the QVGA type color lcd's. The 13705 series is quite good.
However, my recommendation (if you are still open to a CPU) is to use the Samsung or Sharp ARM7 solution which comes with the built in LCD controller. Cost is much less with this solution and usage is easier.
With an external LCD controller, you have to deal with additional wait states which makes the system slower. With an integrated solution, the speed is good AND coding is easier.

Actually, Cumtomer want to use STN LCD from Casio (CMD500TT10-C1) with the ARM9 board. So, the LCD Controller will interface between ARM9 CPU and LCD Display. And we have to develop a custom device driver on uClinux.
BTW, Thank you very much for your advise. I will take a look at the controller from epson.
