In the early stages of the Xen ARM port we had intermittent problems
with varadics when the stack pointer got misaligned -- the toolchain's
code for laying out stack arguments assumes that the stack pointer is
properly (i.e. 8-byte, on 32-bit ARM!) aligned to start with, and can do
some confusing things if not.

Cheers,

Tim.
