Mark,

You can use the gdal_merge.py script to "stack" files into a multi-band
file.

eg.

gdal_merge -separate -o stack.tif band1.tif band2.tif band3.tif

The -separate tells the script to put each file into it's own band.

There is also a "Compose Dataset" tool in OpenEV (in the Image menu)
that apparently does this process, though I haven't used this myself yet.

Both are available in FWTools builds.

Best regards,
