So, looking at this again, the proposed patch certainly seems consistent with
various other sources, e.g.:

http://peterdn.com/post/e28098Hello-World!e28099-in-ARM-assembly.aspx
https://wiki.debian.org/ArmEabiPort
http://en.wikipedia.org/wiki/Calling_convention#ARM

Patch applied.

Cheers,

Michael
