Last I checked the A20 only goes up to 960MHz or so:

% cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 
144000 312000 528000 72 864000 912000 96 
% 

You can try to overclock it, of course.

Then you have seen bad the FRD450. The size of FRD450 is 60mm x 109mm.
The size of FRD3975 is 57.5mm x 97.20mm.

Good luck with your project!

I was referring to the module size, not viewing area.

Yes, a handheld computer but not clamshell. My plan is to make
something more like a Blackberry/Peek/Nokia E71. Screen above qwerty
keyboard.

The active area of FRD450 is 55,44mm x 98,64mm. The active area of the
FRD3975 is 51,84mm x 86,40mm. Maybe you have seen something wrong.

Is your project a handheld laptop like OpenPandora/Pyra?

Your datasheet is a bit hard to read, but I think it shows size as
100mm x 56.?mm. The FRD39751040V datasheet states 97mm x 57mm. They
both seem quite close in size and I might be able to use the larger. I
have not done a case design yet so I'm not dead set on anything.

Yeah, there it is. I just ran it smoothly on my Beaglebone Black (1 GHz). I've 
yet to try PrBoom on my Raspberry Pi B+ (700 MHz), but I'm guessing it will run 
well on the EOMA68-A20 with it's 1.2 GHz.

There's Prboom-plus in the official Debian repository.
