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]).
