LCD module driver

V0.152, 15. June 1999
------
 - Added new delay function in order to reduce system-load. It will call
   schedule() in order to let other processes run on longer delays. This
   saves just 0.1% CPU time on my 533MHz Alpha. Maybe this can be more on
   other machines.
 - Minor driver change for proper compiling with 2.0.* kernels (oops ;)
 - Added some Makefile additions for the driver and a new program in the
   tools/ directory (lcdtime).
   Thanks go to Chris <[e-mail]> for this!
