Could you try to add the following line in machine_kexec.c, just before

machine_kexec.c is in the kernel not in the kexec userland tools.

Aah, I see.

Anyway, it doesn't work - with or without this slight change in machine_kexec.c, with kexec compiled from the sources in the link you gave or with kexec-tools-testing-20080324, it just doesn't work on BCM43XX with OpenWRT patches. At least on Asus WL-500gP.
