See my patch http://www.mail-archive.com/fastboot@lists.osdl.org/msg03054.html.

The problem was that reading out the symbol table is not a very clean way to
get the command line size of the kernel. I think we should still make sure that
new kexec runs with old kernels properly.

However, since the command line size is now in the x86 boot protocol and we
must currently use bzImage to load the relocatable kernels anyway, it may be a
good start to detect the command line size for bzImage and allow larger values
for that.

I can make a patch for this, but in the next year.
