"Experimental" means that it doesn't seem to work at the moment. - regs4740.h (_LCD, LCDCTRL): added the LCD control register - ubb-vga.c (old_lcdctrl, tame_lcd, restore_lcd): make the LCD controller use short bursts, to reduce the bus access latency for other users - ubb-vga.c (keep_lcd, setup_noirq, cleanup_noirq, usage, main): new option -2 to keep on refreshing the LCD display
