[Tremor] different tremor output on armel

I'm seeing different tremor results on the armel platform, using
ivorbisfile_example.c from the repository.
I recorded a very small wav file, used oggenc on a machine with an FPU
to encode it to vorbis, and then used the ivorbisfile_example.c to
transform it into raw data.
I did this final re-encoding to raw data on three platforms: i386,
amd64, and armel, all using debian systems, with libvorbisidec from the
debian repositories, which themselves are straight builds from SVN r15687.
I've published the results here:
(you can fetch the files individually, or you can pull down all of them
in a tarball)
I found that the results from i386 and amd64 were identical (as
expected), but that the armel results were dramatically different
(significantly quieter, fwict). Any ideas as to why this might be?
The armel platform as an NSLU2 with 32 MB of RAM, FWIW. All tests were
run as non-privileged users.
Can anyone else reproduce these results?
