4 MB seems to be the maximum. So 1600x1200 is the maximum with kzalloc() at the moment:

	dlfb_video_modes[3].col = 0;
	memcpy(&dlfb_video_modes[3].hclock, "\xCF\xA4\x3C\x4E", 4);
	memcpy(&dlfb_video_modes[3].vclock, "\x55\x73\x71\x2B", 4);
	memcpy(&dlfb_video_modes[3].unknown1, "\x71\x52\xFF\xFF\xEE\xCA", 6);
	dlfb_video_modes[3].xres = 1600;
	memcpy(&dlfb_video_modes[3].unknown2, "\xE2\x57\xFF\xFF\xFF\xF9", 6);
	dlfb_video_modes[3].yres = 1200;
	memcpy(&dlfb_video_modes[3].unknown3, "\x04\x02\x90\x7E", 4);
