You want
 Visual     "TrueColor"
in the "Device" section.

I don't know who started the idea of "8,24" v "24,8" but it doesn't appear 
to have been implemented.

The reason why the 8bit visual is the default is that many of the apps 
which need an 8bit visual are too stupid to look beyond the default :-(.
