16 bit depth is unversally broken at least whenever the fbdevhw driver is
used. Part of the problem seems to be that the kernel driver is only
passed the pixel size (bits_per_pixel) which is 16 for both 15 and 16 bit
depth. The fb_var struct doen't have a separate field for depth. But
that's not all - I've tried a variety of hacks to make the kernel driver
use the 16 bit depth to no avail. Some part of the X server appears to use
the wrong depth ...
