- *
- * 0.3.2
- * - got rid of all floating point (dok)
- *
- * 0.3.1
- * - added module license (dok)
- *
- * 0.3
- * - hardware accelerated clear and move for 2200 and above (dok)
- * - maximum allowed dotclock is handled now (dok)
- *
- * 0.2.1
- * - correct panning after X usage (dok)
- * - added module and kernel parameters (dok)
- * - no stretching if external display is enabled (dok)
- *
- * 0.2
- * - initial version (dok)
- *
- *
- * TODO
- * - ioctl for internal/external switching
- * - blanking
- * - 32bit depth support, maybe impossible
- * - disable pan-on-sync, need specs
- *
- * BUGS
- * - white margin on bootup like with tdfxfb (colormap problem?)
