old vs new(V7) BarChart3D

I've been using BarChart3D in pre-7 versions of Mathematica to produce
density plots for discrete probability distributions.  For example,

 BarChart3D[
(binorm = {{4,15,24,15,4},{15,60,90,60,15},{24,90,144,90,24},
	 {15,60,90,60,15},{4,15,24,15,4}})/Max[binorm],BarSpacing->.5,
Boxed->False,Axes->{False,False,False},
  BaseStyle->{Medium,FontFamily->"Arial"},PlotLabel->"Field Study"]

Pre V7, this generated nice, histogram-like bar bars.  But now it
generates what I would call a microsoft-like two-dimensional bar graph
with a fake 3rd dimension that conveys no information.  I want the old
one back!  I've discovered I can get the old one back by using

 Needs["BarCharts`"]

but then I get all sorts of compatibility warnings.  Is there
something else I should be using instead of the new BarChart3D[] to
generate something like the old style BarChart3D[]?  It is not
Histogram3D because I already have the probabilities or counts for
each data point.  Histogram3D wants raw data that it will bin for
you.  Any suggestions?  Or should I just load the legacy version and
ignore the warnings?
