Carlos O'Donell and myself looked at this problem this afternoon.  This
is a dietlib problem.  Dietlib is not using the correct kernel_stat
mapping for parisc.  They appear to be using the i386 mapping.  They
need to look at /libc/sysdeps/unix/sysv/linux/xstatconv.c and the
hppa/kernel_stat.h header in glibc.
