Here is the dirty hack if someone else is also making posters with orgmode &
beamerposter.
Unfortunately I know AWK better than elisp so don't condemn me :-) It does a
perfect job for me. I don't know if can be hooked to pipe through before
writing TeX output.

#!/usr/bin/awk -f
# Post-process orgmode output before final call to pdflatex while using
beamerposter

BEGIN {
    end_block = 0		# 1 if previous line was \end{block}
    columns = 0			# 1 if probably \vbox will be needed, 2 if
it is needed
    RS = "\r\n"			# I'm on Windows
    height = ".98\\textheight"   # FIXME
}

/^\\frametitle{.+}$/ { next}	# frametitle removal from the only frame

/^\\begin{columns}/ { columns = 1 }
/^\\begin{column}/ && columns { columns = 2 }

/^%% .+/ && columns == 2 { print "\\vbox to " height " {%"; columns = 0 } #
we rely on orgmode comments :(

/^\\end{block}$/ { end_block = 1 }

/^\\begin{block}/ && end_block { print "\\vfill"; end_block = 0 }

/^\\end{column}$/ && end_block { print "}%"; columns = 1; end_block = 0 }

{ print }
