- * --------------------------------------------------------------------------
- * 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
- * --------------------------------------------------------------------------
+ *
+ * and additional input from James Simmon's port of Hannu Mallat's tdfx
+ * driver.
+ *
+ * $Id$
+ *
+ * I have a Creative Graphics Blaster Exxtreme card - pm2fb on x86.
+ * I have no access to other pm2fb implementations, and cannot test
+ * on them. Therefore for now I am omitting Sparc and CVision code.
+ *
+ * Multiple boards support has been on the TODO list for ages.
+ * Don't expect this to change.
