* History:
* 1999/05/09 added Jim Hague's 'var' kernel option (thanks Jim!)
* 2002/04/23 Jim Hague <jim.hague@acm.org>
* * Integrated Illo's last changes, No changelist available.
* Major items: acceleration support, hardware cursor code
* (not yet enabled).
* * Fixed -vsync, added lowhsync/lowvsync overrides for use with
* XFree GLINT driver.
* --------------------------------------------------------------------------
* TODO multiple boards support
