Poke a few more bits into the ch7xxx to make it output a picture after being reset during S3. In particular we need to set the input buffer select (IBS), and enable VGA vsync output on the BCO pin. Selecting VGA hsync on the c/h sync pin doesn't actually seem necessary on my ADD card at least, but the BIOS selects it so why not.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
