I might have got confused, but it looks to me like patches 27 and 28 basically undo patch 26: in 26 you moved code to hd44780 and wrote a fallback, just to later delete that code. I seem to remember that the reason for the clear_fast() implementation is that the default clear_display() is quite slow for small displays, compared to what can be achieved by just filling the display with spaces (in the order of tens of milliseconds vs hundreds of microseconds). But I could be mistaken given how old this is, so please take my comment with a grain of salt. Willy
