Thanks for your patience Amos; I believe the commits I just made should
solve your problem. Basically removing the boot wrapper (and that's
bugged me for a while for other reasons) allows us to collapse three
command line buffers into one, and that makes me happy. :)

bicl (http://www.cs.unm.edu/~k42/tools/bicl) acts directly on the
command line that was built in at compile time. If that buffer is empty
at runtime, firmware arguments will be used.

Note that changing the CMDLINE at compile time does not properly replace
the previous CMDLINE; you would have to make clean or remove
xen/arch/powerpc/cmdline.o by hand. I'd happily accept a Makefile patch
for that.
