I think, her is the catch: 512k videoram = 512*1024*8 = 4,194,304 bit!!
resolution 1280 * 1024 = 1,310,720 pixel
so are there 4,194,304/1,310,720 = 3,2 bit/pixel
That's just enough for monochrom (but 3 images).
Find out, how much RAM the videocard really has and set it in XF86Config
as described in man XF86Config by hand: VideoRam mem
