Can you try with the patch :

  * programs/Xserver/hw/xfree86/common/xf86cmap.c:
  Fix tests for maximum number of colours when creating a colourmap, so a
  32-bit visual (e.g. ARGB) doesn't overflow an int when attempting to do
  1 << 32.  (Benjamin Herrenschmidt)

  1.9           +20 -12
xc/programs/Xserver/hw/xfree86/common/xf86cmap.c

That went in a couple of days ago ? There was a bug that could cause
creation of colormaps to fail for 32 bpp visuals.
