You can extract the kernel from your cramfs image by fixing the cramfs support. I just saw that cramfs expects a /dev/ file, that is it expects a devfs file. This could be changed by using regular open/read/write functions. It would be easier though if you live with two files, one cramfs image and one kernel image.
