Have you spent any time reading the datasheet(s) for the 8751 and the LCD? If you're using a "typical" 8751, it's slow enough that the LCD is easily interfaced as an external, memory-mapped peripheral, (see http://pjrc.com/tech/8051/board5/schematic.html) where it can be made to function as a two-byte memory, with one byte specifying the current character address and the other providing the content. You can also specify the address and read the content. If you interface the LCD using ports, just as easy to read the display RAM content.
