Fujitsu Futro S100 - Step 2 - set the frame buffer size

By default, the Futro's BIOS is set to reserve 128MB of the RAM as a video frame buffer.

The Futro is capable of displaying video at 1920 x 1200, but I'm using an old LCD screen with a maximum display of 1280 x 1024 LCD monitor I have.

I like as much screen real-estate as possible, but I don't need much in the way of colour, so I used my patent frame buffer sizing formula and came up with 16MB.  At that setting, Xorg allows me to select 1280x1024 at 16bit colour depth.  I'd be happy to run with about 8 bits of colour depth, but Xorg doesn't offer that.  And if I want the 24bit option that Xorg offers, all I have to do is set the frame buffer to 32MB.

This frees up an extra 112MB of RAM!
