Driver for 320x240 color graphic lcd?

I have some Hantronix HDM3224ATS-C-JST color touch LCD panels. The closest appnote I could dig out of the website was for a similar monochrome unit. It listed some driver chips, but they are all out of production.

Can anybody recommend a driver chip that I can buy or sample in small quantities, and preferably somebody has interfaced to an Arduino?

Thanks!
