Even > Take a closer look at the actual pixel format of the PXA270. The usual graphics packages AFAIK support either packed pixels (i.e. 18 bit on screen => 18 bit in memory) or unpacked (i.e. 18/24 or whatever bits => 32 bit in memory). The PXA supports either the unpacked pixel format (which is a waste of memory especially on embedded systems) or a strange format which is neither: 18bit on screen in 24bit in memory (IOW 4 pixels in 3 words in memory).
