Hi,

you actually have to do the following modification modifications. 

First you have to modify the function au1100fb_setcolreg, add the switch
case for 4bpp. Look in the Alchemy manual for the format of the palette
in the 4 bpp case. Then look for my comment "TODO: 8bbp", put a switch
and for pseudocolor like visual ... I think this is not even necessary.
More important is that you change the monitor type. If you want I can
send you privately a patch this weekend, but I just cannot assure it
works, you have to test it and eventually contribute.
