I don't think so.  That modules directory should be removed by the
upgrade and that would cause that error.

The only things in the i686 and athlon directories are packages which
have some differentiation based on architecture.  That's really just
the kernel and anything with dependencies on the kernel.

Yes.

The i386 kernel *should* work on any about anything.  I've seen cases
where it wont (highmem + athlon doesn't work with the x86 kernel).
It's probably possible to run an athlon kernel on one machine and have
it work with another box running the i686 kernel.

The issue there is the differing FPU types.  You might get an oops
migrating with that version of BProc.  This has been fixed but only
recently.

The beoboot kernel is ONLY for phase 1 boot images.  It's a stripped
down good only for booting slaves.  It doesn't include things like
disk or ext2 support.  You shouldn't see it on the grub screen.

The phase 1 images are only if you need to use a floppy.

*shrug*  You're going to have to elaborate on "failed".
