There is also an (unrelated) problem with pseudo-device rnd and the
arm32 port.  I'm going to hack on it later today, once I'm near an
arm32 with an IDE drive.

Do you have any hints on what might be causing it?  Usually it is a
problem when the upper layer allocates structures for the lower layer,
but doesn't #include "rnd.h" first, so the structures it allocates are
smaller than they should be.
