Sony ACX705AKM up the prop's ally?

This LCD has been around for a while and there are a couple different controllers for it. You can buy them from http://store.earthlcd.com/ACX705AKM-7-ACX705AKM7?sc=7&category=6
I was looking through the specs and see its quite similar to the VGA output existing on the prop (with dot clock added) and I'm wondering if anyone has thought of using it?
A 320x240x4 color·VGA display requires 320/16 *·240 * 4 bytes = 19,200 ram for the bitmap. The 240x160x4 would only require 9,600 bytes for the same color depth. However, while vga runs at ~25 mHz, this LCD is ~14 mhz, meaning almost twice as much processing time available.
If the prop can put out the 8 bits (6 color, two sync) at 25 mHz, could it not put out the 12 bits? (9 color, two sync, dot clock?) at 14 Mhz? Oh, and handle the touchscreen of course [noparse];)[/noparse]
I'd be attempting it myself but I just have no understanding of assembly at all.
