[Rtai] uImage out of zImage

I use this Kernel, because I want to build a RTAI-patched Kernel for an ARM-Board, and the newest Kernel RTAI offers patches (Arch = arm) for is 2.6.20. I know about the disadvantages, but I see no other way. If you know one, please tell me!
How can I use this uImage? After Cross-Compiling only a zImage was created, so I thought it might be clever to transform it into an uImage. Isn't there a possibility to do this? With the command I wrote in my last Email I thought it should work...

Thanks so far, Jens

Why don't you use the uImage target the Linux kernel offers?

And you should _really_ consider using a more recent kernel unless you
have a good reason not to do so. 2.6.20 is indeed ancient.
