kexec/Kdump for linux

Hi all,
I see in the linux source - 2.6.22 that there is kexec support in
the kernel for ARM architectures. I tried to back port it to a source
based off 2.6.10 or earlier. But I also observed that kexec tools
avaliable are only for x86 and ia64 architectures. Before I start off
on porting anything to ARM I am trying to know if I there is any work
done on kexec for ARM architecure. If anybody has ever used any of
the kernel dumping mechanisms for ARM architectures, I would
appreciate any information...
Thanks,
Ram.
