Great! This is what I was looking for!
Where did you learn about it? It's not
listed in http://www.gdal.org/gdal_utilities.html
Thanks!

to produce layer stacks you can use gdal_merge.py, e.g.:
gdal_merge.py -v image.tif -separate blue.tif green.tif red.tif
I recommend gdal_vrtmerge.py [1]. It produces a "virtual raster" (vrt
format) which can be loaded into QGIS. The vrt file is just few lines
text, doesn't duplicate your input data, but apart from that it behaves
pretty much like a multiband GeoTIFF.
Use it like:
gdal_vrtmerge.py -separate -o tm2.vrt *.tif
(Without -separate it will fail [2]).
