- * STATUS:
- * 11/09: lc: Only basic keyboard is supported, mouse still needs to be done.
- * 11/12: tv: switching iomapping; cleaning code; improving module stuff.
- * 11/13: lc & tv: leds aren't working. auto_repeat/meta are. Generaly good behavior.
- * 11/15: tv: 2AM: leds ARE working !
- * 11/16: tv: 3AM: escaped keycodes emulation *handled*, some keycodes are
- * still deliberately ignored (18), what are they used for ?
- * 11/21: lc: mouse is now working
- * 11/29: tv: first try for error handling in init sequence
- *
- * TODO:
- * Error handling in init sequence
- * SysRq handling
- * Pause key handling
- * Intellimouse & other rodents handling (at least send an error when
- * such a mouse is plugged : it will totally fault)
- * Mouse: set scaling / Dino testing
- * Bug chasing...
