Your system seems to shift bignums correctly. I looked
through gumstix' patches for gcc-3.4.2, and they essentially
match what I'm using with gcc-3.4.4. So I'm leaving towards
the theory that the bug was introduced after gcc-3.4.2.

The gcc/arm maintainers have confirmed the bug, but no patch
has been published yet.
