You have missed out the encoding that VNC would actually use over a 56K
line - ZRLE.  ZRLE performs at least as well as Tight over slow
connections, and was introduced in VNC 3.3.4, which is why there's been
no need to add the Tight encoding.

VNC 3.3.4 and above will auto-select the encoding and colour depth of
the connection based on the apparently available bandwidth.
