I haven't had problems with flannel in smaller sizes just using my standard sewing machine.
I am on the homequiltingsystems group at
http://groups.yahoo.com and quite a few of the quilters there have successfully used flannel for backing. I don't have a frame system myself, but I know there are different ways of setting up sandwiches for quilting -- full and partial floats, side tensioning, etc. Someone on that group should be able to help; perhaps even someone with your machine and frame.
