It looks like the VGA resolutions that are supported can be changed by
altering the list in the code that emulates the Cirrus VGA.

But easier than that is to direct Anaconda (the Fedora Linux
installer) to use a lower resolution.  That doesn't work as smoothly
as it should, either, but this procedure works:

    To fix this, the install system needs to run with the boot parameters
    "nomodeset resolution=1024x768".  To do this, at the start screen, use
    the arrow keys to select "Install", then type Esc.  This gives the
    prompt "boot:".  Give it the command "linux nomodeset
    resolution=1024x768", then type Return.

Since I am not installing X Windows, when I boot the resulting Linux
system, it comes up in text mode with a low resolution.
