Not clear how large off screen memory we want to dedicate. I expect we

The geode graphics can only touch stuff inside the window; but memory to
memory copies aren't that expensive, so I'm not convinced that we'll
want to dedicate the full 16Mb.
That isn't the problem. That driver just assumes a BIOS setup, BIOS firmware,
BIOS emulated video PCI port (at least on the stuff here it is emulated, there
is no real PCI device it is talking to), memory layout, PLL setup, video
layout etc.
And all I'm saying is that we can fix that. First, though, I want to be
booting a linuxbios-based kernel, and then kexec a test kernel with the
fbdev driver.
