An LCD for Freebee

I've got this idea for making a coreboard that plugs in to freebee that contains it's own LCD controller. I can buy (from Core electronics) a lovely little 10" 1280x800 LCD, with a converter board that takes a VGA input. If I do 2 pixels per bee pixel horizontally, and 3 pixels vertically, I get a 640 x 266 display, which is terribly close to the 80x24 bee mode (640 x 264).

I bought one of these (panel is a B101EW05), and this is what it looks like on freebee, via a GBS-8200 CGA-VGA upscaler. It's not too shabby:

the data sheet for the panel says it works with dot-clocks from 64-85 MHz, so at (say) 80 MHz, halving horizontal resolution, I only have to generate pixels at 40 MHz. That's doable with 74AHC...
