Yes, the patch works but there are still issues and I can't get the display yet alive: [ 4.081390] n8x0_panel display0: invalid s1d1374x revision 00 [ 4.087738] omapfb omapfb: Failed to enable display 'lcd' [ 4.093475] omapfb omapfb: failed to initialize default display For some reason all the blizzard_read_reg()s return just zeroes. I have set up the panel_reset and ctrl_pwrdown GPIOs (30, 15) according to the Maemo kernel, but maybe there's still more initializations I need to do from the board file... > I haven't tested N800 for ages, as I don't have a serial console for > my N800, and last times I've tried I didn't manage to get it to boot. It works. I use busybox/dropbear/USB networking to get a "console". A.
