Hi,

thank you. Two points:

   1. Please refrain from using the semaphore stuff. It is ancient code
      used to mediate access between LCDproc and  programs called
      'lcdtime' (and I think 'meter').
   2. I am a little reluctant adding drivers for ready-built cases
      (especially if appliances are used for something else than
      originally intended). From the drivers we ship I learned that the
      devices are only available for a short period of time. Therefore
      those drivers have limited use for others.

On the other hand adding a new connection type to the hd44780 driver
adds only minimal bloat. If you make it without the semaphore stuff I
will be happy to commit it.
