MPC5121E DIU DESC issues

Using a Phycore MPC5121 tiny, the area descriptor  settings I see from u-boot/linux don't make any sense.  In particular the Bitmap Address when it is running with the penquin displayed is 0x0000A00F for area 1 and 0x005090F for area 2/3.  Maybe I'm being naive, but I thought these had to be word aligned.  Changing 0x0000A00F to 0x0000A00C with an emulator destroys the display.  

 

Also, setting values into the cursor Bitmap has no apparent affect. 

 

What am I missing?  Does anyone know where to get more documentation on this?
