  *           with modifications by Stephen Blackheath (Aug 2002)
  *          
  * REVISION HISTORY:
- *   December 2001 - Patrick LERDA's original (http://sourceforge.net/projects/i740fb).
- *   27 August 2002 - Patrick's version would run for an hour or two on my machine,
- *     then the screen would go blank (no signal to monitor) and for some reason I
- *     sometimes couldn't even log in through the network.  I had to re-boot my machine.
- *     This version fixes that and makes a few other unnecessary tweaks.  I am not
- *     certain, but I think the problem is that Patrick's code was reading a value from
- *     XRX register 0xD0, and or'ing with 0x10.  When I removed this from the main
- *     loop, it became reliable.  I suspect the hardware (whether just my cheap
- *     clone board only I'm not sure) was sometimes returning bogus values, which were
- *     then programmed back in - but I never checked this.  This register is related to
- *     powering on or off certain subsystems of the i740 chip, so that might explain
- *     the blank screen. - Stephen Blackheath
- *   3 September 2002 - Added software scaling in the situation where the screen size is
- *     smaller than the original video size, since scaling down is not supported by
- *     the hardware.  The implementation of this is not quite complete.
- *   12 September 2002 - Better software scaling with some averaging, giving a nicer
- *     picture.
- *   13 January 2003 - Fixed a minor bug where the video would occasionally stop updating,
- *     which was worked around just by re-sizing the window.
+ *   December 2001 - Patrick LERDA's original i740fb project on SourceForge.
+ *   27 August 2002 - Patrick's version would run for an hour or two on my
+ *     machine, then the screen would go blank (no signal to monitor) and for
+ *     some reason I sometimes couldn't even log in through the network.  I had
