Based on fs/cramfs/README, it doesn't look like cramfs images
are very portable, so I'm probably just rediscovering a known
problem.  x86 and ia64 are both little-endian, but x86 uses
4K pages while ia64 uses 16K pages.  Maybe that accounts for
the problem.

I also noticed that when I mount the x86 Ubuntu cramfs image
on the ia64 RHEL4 box and read a file, cramfs complains about

  Error -3 while decompressing!
