Err, what?

I could imagine this happening if the kernel and the loader got out of 
sync.  The alignment of the MODINFO_* tags was changed from int32_t 
alignment to int64_t alignment for the benefit of the alpha.  vm_offset_t 
is 64 bit there and can't be accessed on non-natural boundaries.

There are a couple of other problems that i've found.  Some long-standing
bugs in the kern_linker.c code and the link_*.c modules turned up.

Cheers,
-Peter
