No, alpha fails because of lp64-ness.  We've got misalignment support.

Actually, it fails on x86_64 becuase 64-bit implies sse, which we're
not turning off.  And I have a patch to implement misalignment support
for sse (which I'm not totally happy with), and then x86_64 fails 
because of lp64-ness.
