Only if you use proto_tree_add_XXX_format().  Ethereal's standard 
display format for bitfields is the dotted presentation, so you have to 
bypass Ethereal's standard formatting to get anything else.

Alternatively, you could add fields that *aren't* bitfields, and do your 
own masking and shifting and use proto_tree_add_uint(), etc. to add the 
item to the protocol tree.
