It sounds like you need to write a driver for your LCD controller chip...

If you look at the code which actually displays the image (don't have my
source tree handy right now) you'll see that it takes the palette data and
expands it out to the appropriate colors depending on the type of display
color setup you have.  We have it working fine on a 32 bpp display which
is 8-8-8 color, but the principle is the same for 5-6-5.
