By kernel loader I mean the bootldr kernel loader hence the params.h
refers to the bootldr source not the kernel source.

It has worked for me in the past with board=aleph1 and I believe it has
worked for David Bisset with build=hydra using my kernel builds but the
message is not encouraging.
If I do a "set build=guralp" "params save" and "reset" I get the
expected result using my bootldr and 2.4.25... .
What does cat /proc/balloon_board report for you?

Yes, see above.
