The other possibility is that if you can use Photoshop or an image
viewer to pick out the pixel locations of your GCPs in the image, and
you know the geographic locations of those GCPs, then you can construct
a GDAL VRT file and use gdalwarp from the command line to warp your
images to the GCPs. This is probably your most flexible all around
option, assuming the MetaCarta Labs Rectifier doesn't do it for you.
