Hmmm...I seem to be having some trouble setting "mem=" (system hangs).
Maybe multiple "mem=NNNK@0xXXXXXXXX" options won't work.

While I try to figure out what's going on, here's a program ("kargs")
that composes a kernel command line from the contents of
"/proc/cmndline" and "/proc/iomem". It doesn't do as much error
checking as it should...

Usage (sh quoting): kexec --force "--command-line=`kargs`" bzImage
