The reason vm-mime-show-alternatives arose can be understood from this thread:

http://groups.google.com/group/gnu.emacs.vm.info/browse_thread/thread/230530b5570a30e9/e4a33090647e58a7?lnk=gst&q=uday+multipart#e4a33090647e58a7

It is a wrapper that makes multipart/alternative look like
multipart/mixed. The VM's internal code doesn't know anything about
it.

I am still wondering why you can't just view text/html and forget
about the text/plain parts.

Cheers,
