John,
The 'booktabs' argument is for print.xtable(), not xtable(). Easy mistake.
Thus:
> print(xtable(aa), booktabs = TRUE)
% latex table generated in R 3.0.1 by xtable 1.7-1 package
% Fri May 24 14:40:07 2013
\begin{table}[ht]
\centering
\begin{tabular}{rr}
\toprule
& V1 \\
\midrule
a & 9 \\
b & 8 \\
c & 17 \\
d & 9 \\
e & 7 \\
f & 16 \\
g & 13 \\
h & 10 \\
i & 11 \\
\bottomrule
\end{tabular}
\end{table}
