The function heatmap.plus (library: heatmap.plus) can do that, just
combine the different color vectors with cbind(col1,col2). Unfortunately
the arguments required for heatmap, heatmap.2 and heatmap.plus are
slightly different.

For example, I can make one side color bar (col1) with the following code:
