This driver in the Code Library forum looks like it could work,
or it could be modified to work with your LCD:

where is the mistake?
Code:
void glcd_pixel(unsigned int8 x, unsigned int8 y, int1 color)
{

   BYTE data;
   write_command( x);                     // Set the horizontal address
   write_command((y/8 & 0xBF) | 0xB8);   // Set the vertical page address

   if(color == 1)
      bit_set(data, y%8);        // Turn the pixel on
   else                          // or
      bit_clear(data, y%8);      // turn the pixel off

          // Set for instruction
   write_command(x);      // Set the horizontal address   
   write_data(data);   // Write the pixel data;
}
