You also need to properly program the EZ328 to give the LCD the proper
timings / layout, here is my crt0_rom.S initializations for the LM32019
display:

#if INIT_32019_LCD
        /* this is for the LM32019 display. */
        movel #splash_bits, LSSA_ADDR /* LCD starting address. */
        moveb #0x14, LVPW_ADDR /* LCD Virtual Page Width Register. */
        movew #0x140, LXMAX_ADDR /* LCD Screen Width Register. */
        movew #0xef, LYMAX_ADDR /* LCD Screen Height Register. */
        moveb #0, LRRA_ADDR /* LCD refresh rate. */
        moveb #1, LPXCD_ADDR /* LCD Pixel Clock Divider Register. */
        moveb #0x08, LPICF_ADDR /* LCD Panel Interface Config Register. */
        moveb #0x00, LPOLCF_ADDR /* LCD Polarity Configuration Register. */
        moveb #0x81, LCKCON_ADDR /* LCD Clocking Control Register. */
        movew #0xff00, PCPDEN_ADDR /* LCD pins Port C Pull-Down enb. reg */
#endif
